Teresa, I don't have a definite answer for you, but anecdotal evidence when this type of issue has been encountered is some confusion/conflict with caching of definitions on the mid-tier or user's browser. The problem can come and go - but does tend to occur when there has been a change to a form.
The best suggestion I have is to consider upgrading to the 8.1 sp2 version of the mid-tier. JUST the mid-tier is needed. You do not need to upgrade anything else in your environment. We found some behavior of caching that was unexpected and we added additional logic to work around that in the 8.1 sp1 release and fixed one final issue with images in the 8.1 sp2 release. The biggest unexpected behavior was with how browser caches work. We have dynamic pages that change contents but do not change the URL. Well, the way things work in the browser cache is that if the URL is not changed, then the system is happy with a cached copy of the page and doesn't get a new one. So, until things timeout (generally in the 1 day range), there is a mismatch. We have added additional logic to check independently of the browser caching and force an update if there has been a change in the newer version of the mid-tier logic. We have found that the different issues of not showing changes or of showing pages that were partially there or similar issues have simply stopped happening with the 8.1 sp2 or later version of the mid-tier. Customers who had repeated intermittent problems no longer have them. Customers who had to frequently "flush cache" on the mid-tier to bring back consistency no longer need to do that. I cannot say for sure that you are encountering issues that this upgrade will help. I can say there is absolutely no downside to an upgrade of the mid-tier and it does not affect the applications or server or the running of your server or applications. (OK, there may be if there is some minimum version of some browser or servlet engine that changes between the release you are on and the 8.1 sp2 minimum versions and you must support earlier versions - and then you can have some 8.1 sp2 midtiers and an older midtier and have folks with say the older browser versions go to the older midtier and everyone on more current versions go to 8.1 sp2 midtier). Just some thoughts and ideas. You may consider doing a "flush cache" operation on your midtiers (you must do this on all of them if you have multiple) and clearing the browser cache on users who are having the issue will correct the problem for the moment. So, that could be an immediate workaround. Some ideas to consider....

In 8.1.0 when some of our uses login to ITSM and they go to create an Incident and the display has everything in it Except the Tabs are not displaying at all. They can still create a ticket if they use the quick links to create their Operational Cats and Product Cats. The process bar is still there but the tabs that go under that are missing. We have tried to recreate the people record and that has worked for some but we still have others that it is not working for. We just went live this last weekend.
