Apologies if this has been discussed, I did as good a search as I could.
This has been a recurring issue for me through many versions of LR and Mac OS and still with latest versions of both (OSX 12.4, LRC 11.4.1).
When I'm previewing my recent import and 'Rejecting' (X) and 'Adding to a Collection' (B), advancing through the images with the Arrow-keys, LRC will, for what seems to be a random period, skip the next JPG version of the file and go from one RAW to the next. I can't say with certainty if it also skips RAW versions between JPGS but I definitely noticed the JPGs being skipped yet again this morning. There is, what looks like, a momentary screen redraw or 'jump' when this happens.
I am aware of the pace I press the right (advnace) arrow key and I'm not doubling up, it is the app.
Needless to say I find this frustrating. It is an incumberment to a smooth workflow.
The setting for treating JPG and RAW versions as separate is checked.
Any ideas? Is this a bug or the result of some setting or practice I'm missing?
