[otrs] CI - not able to add a new "class"

Hi all, It was a long time that I had no need to use it but now it seems that I'm not able to define a new class in CI (2.1.94 - migrated, not new. Let me say that I have not used it since it was in the previous version... so "add" could be elsewhere ;) ). I'm doing something wrong or it could be a config error ? (See attached image, there is no add new) Thank you for any suggestions you may give me. MV
