This is not a bug. It is a behavior which is annoying in many cases,
including yours. There is no workaround. Unfortunately, you'll have to
remove "collapsed: yes;" and "collapsed: no;" in order to make it easier
for your users.
Here's what happens:
Depending on the CSS selectors referencing geov|grp, its attributes and
its child elements, XXE may be forced to recreate the view of geov|grp
when you add or modify one of its child elements. And when a new view is
created for geov|g...@presence != 'mandatory'}, it is automatically
created in collapsed state.
