Hi Katy:

That's great news that the upgrade completed successfully!

On this question, I'm also puzzled. To be extra clear, is that XML in the samples schema for your Sample Type? With the correct <table> and other syntax surrounding it - but nothing else there? You shouldn't need that to be there at all, though it looks correct to me, so removing it entirely . And there is nothing in the XML for exp.materials for that type? You mentioned earlier that fields were working (showing up) on your dev instance of 24.3.4, but now they aren't? Or they aren't on this server? Is this true for all Sample Types? If you create a new one with nothing new/special, does it also hide that field on insert?

Something specific must be different about this Sample Type, or this type on this server in this container, and it's hard to know what that might be without looking at it in person. You're probably right that a user-defined field would work for you just as well. Or if a newly created Sample Type works correctly, then rebuilding your type from that and migrating the data could be another workaround.
