Sigma 30mm f/1.4 DC DN for Canon EF-M bug?

Hi, everyone:

I bought the Sigma 30mm f/1.4 lens for Canon EF-M in May 2020. I do not know what is the firmware version (I do not have the Sigma USB dock). I have the Canon M6 Mk2 with firmware 1.1.0 and Canon M50 with firmware 1.1.0. I see the same issue with both cameras:

ExifTool reports the following:

LensModel: 30mm F1.4 DC DN | Contemporary 016

LensType: Sigma 56mm f/1.4 DC DN | C

The same issue happens on both bodies, with C-Raw files and with jpegs.

Does anyone else have this lens and encounters the same issue? Does it have any effect on the performance of the lens in any way?

Thanks for any input.

Canon EOS M50 (EOS Kiss M) Canon EOS M6 II Sigma 30mm F1.4 (E/EF-M mounts)
