Duplicate tracks in playlist

I am getting this on Engine Prime on my iMAC. I copied half my library over to a USB and since then the majority of tracks in the collection on the iMAC are duplicated, even ones that were not copied. They files all point to the same location on the local drive. When I mount the USB, those tracks which are in the collection and on the USB are presented three times. Is this still the same bug which has been around since early 2019?
