Metadata writing in progress (n files pending).... error

After updating to the latest version of the Premiere Pro last week, everytime I am closing the project I now get a "Metadata. Metadata writing in progress (n files pending). If you quit before writing is complete, data will be lost. Are you sure you want to quit? Yes/No" error window. Please see a screenshoot attached for one of such errors.

What is interesting, is that no matter how much time i give it the process is never complete.
