Need Answer

After the latest update (did it today, 10.3.2020, the picker extension in Chrome does not show the green mark on the picker symbol on the right side of a DOI number if a paper with a given DOI is already included in the project. If I add this paper to the project, it is not recognized as a duplicate and I have two almost identical references.

I tried disabling and enabling the extension in Chrome but it results in an error (see attachment).
