Lightroom Classic 7.2: Duplicate Pictures

Noticed that during synchronization, duplicate pictures are being created. This has been going on for some time. Ran tests on several PC's, using the same folder and contained photos. All PC's exhibited the same duplicates using LR 7.2

One PC has an older version as well (5.7), where the same folder was synchronized a few times. The result was quite pleasing, as no duplicates were amongst them. The number of pictures shown agreed with the ones in Windows Explorer.

So I guess the problem is the current version, or any one in between 5.7 and 7.2, as the catalogues were upgraded each time.

Might delete the current catalogue on the standby PC and upgrade the one from version 5.7. See what that brings to light

Have concluded my tests, with the following results:

Opened the catalogue from LR 5.7 and synchronized it about 10 times, to make sure it received all newer pictures.

The result was 10,060 pictures
Opened and upgraded this one in LR 7.2 and once finished, synchronized just this folder once.

The result was 10,150 pictures

Recognized most of the additional photos, as these are the ones that get duplicated after every synchronization. Subsequent synchronization, don't show any more new ones

These 'extra'  90 photo's are visible in windows explorer also as duplicates?
Or are they only show up in Lightroom library?
