It has the same name inside it, but it is a little different.
If it goes through, I've attached a screenshot showing the Keystone
data, the footprint on your website ten minutes ago, and the one I
used successfully.
I uploaded a corrected symbol to my website 15 minutes ago (prior to
reading your
email!!!).
The good news is that the footprint that worked for you is the same as the
corrected footprint that is now on the website.
Thanks for your help.
