LR duplicates pictures while importing

[AMfoto]

Hi Community!

Recently I encountered a very strange problem. I'm currently running LrC 10.3 on a 16" 2019 mpb and OSX 11.2.3
Every time I import pictures via my cardreader Lr duplicates every picture. I checked on the card, there the pictures are "1.cr2, 2.cr2, 3.cr2" and so on. But Lr imports every picture twice, so I have "1.cr2, 1-1.cr2, 2.cr2, 2-1.cr2, 3.cr2. 3-1.cr2" and so on.

I am using the integrated cardreader of my USB-C Dongle that also connects my externam monitor and other peripherals like my wacom etc. but the problem also occures using other cardreaders.

It's really tiresome to always have to delete these duplicates. (No, I'm not doing it one by one, but still...)

Any hints on this?

Oh, and they are all in the same folder, so it's not some sort of backup I think...

In camera, do you have multiple frames named the same way? 

[AMfoto]

No

Two ideas:

1. Reset LrC preferences

2. Create new catalog. See if the same thing happens.

I have the same machine and recently imported thousands of Nikon .nefs without that issue.

Have you made sure that the Make a Second Copy option is not checked? -see screen capture-

Yes

Bring up LrC, double check what version is running.

apparently, pre v10.0 a bug existed that sounds just like what you are experiencing.

Inquiry.

When you import, your source, are you looking under files as opposed to device?

Might be an underlying bug. In that link I just gave (and will repeat) On the last page, that is mentioned (fourth from last)

Using the files option instead of the device option solved the problem.
Never even gave that a thought... Thank you!

What camera? Does it have dual cards? And are you importing via a USB cable? As opposed to card reader.

Also on last page, about 5 reply's down, an odd inquiry byAdobe Tech.
