ADIF Import and DUPES

Kirk, N0KK

Recently I started having issues with the importation of ADIF files.
In this example I import my wsjtx adif file using IMPORT QSOS tab>standard ADIF. When I run this operation duplicates are now added into my log.
Which now forces me to remove all duplicates. Quite a long process.
In the past I'd import this way the dupes were ignored.
Ideas as to what is happening?
