There is nothing to fix, this is not a bug.
When a designer creates a profile they have to select a printer, say P1S, and then make all the tweaks to settings and then upload it, MW will then mark this profile as compatible with X1C, A1 etc
In MakerWorld you come along and select A1 compatible profiles. The P1S profile is listed which you download. That is the P1S profile the designer created so obviously opens as a P1S profile in Bambu Studio, this has nothing to do with what printers you have, it is merely a profile as uploaded by the designer.
All you need to do is switch the profile to A1 and then click “transfer settings” which will copy all the customisations made by the designer into the A1 profile which you can then print in your A1 which you select in the print dialog.
If you print directly from Bambu Handy, it will do the transfer automatically.
