Default metadata plugin error

First post, hope im doing this right!

I just moved my collections to Omeka Classic and I can’t get this plugin to work correctly. I can’t find any posts about it. I run a few image archives and a museum database on the same installation and when i have a collection of ~10 000 similar photos prefilling some fields would be a huge timesave but i get this error message when i try to use it. It seems to show two sets of default metadata settings and none are editable :). I have tried v3.0 and 3.01 of omeka with the same result. Am i doing something wrong or is the plugin nonfunctioning in later versions?

You might want to try reporting the problem directly to the plugin’s developers, to see if they have an idea of what’s wrong.
