RAW+JPEG Import results in HEIC+JPEG import of different photos

[gummelblub]

Lightroom Classic-Version: 11.4.1 [ 202206241800-b406ce4c ]
Mac OS 12 Version: 12.4.0 [21F79]

When RAW+JPEG Import setting is on, HEIC+JPEG got merged in the database as well.

However:

- RAW+JPEG merges only those pictures, which have the same Metadata, thus: only pictures, which are 99,9% identical are being merged

-  HEIC+JPEG merges those pictures with the same filename and neglecting the metadata!

What I did: Imported all my Icloud pictures from 2017/12 to today: Jpeg and HEIC pictures mostly from iphone 6/SE2020/13 + various pictures I received from other owners via Airdrop.

-> There a multiple Pictures with the same Filename: IMG1234.jpg and IMG1234.heic, but they actually are not the same at all (could created in 2018 and 2022).

Luckily I noticed that before deleting too many pairs of pictures.

Expected Result:

When importing JPEG+HEIC do not merge different pictures together only because the filename is the same. Please also verify metadata

Actual Result:

Only because of the same filename, pictures get merged together with the HEIC being shown

Wish:

I really would also like to be able to also see any other file which is "being" a merged dataset. No matter if it is RAW+JPEG or HEIC+JPG.

The merging function can be useful, however it is badly implemented as the only way is to leave lightroom and handle merged files in your OS-Fileexplorer?!
