Journals term list problem in Endnote 20 for Mac

There are several bugs with the “journals term list” in Endnote 20 for Mac. If I use my old library from earlier versions of Endnote, the program doesn’t suggest terms as I type them. It doesn’t update lists during data entry (but it does it with the “authors term list” or the “keywords term list” without problems). If I create a new library, there is no problem with its new journals term list. I can even import the journals list from my old library to this new one, and everything works correctly. The problems only appear with the old library. I have tried to delete the “journals term list”, create a new one and then import the journals list from the older one, but it doesn’t work.
Any help, please?
Thanks in advance.
