Disappearing profiles in ACR

Hi,

I have a load of profiles that I have created in Camera Raw which I use frequently with digital RAW files from my cameras. However, if I try to use them with .DNG files created by Silverfast then most of my profiles disappear from the dropdown list. They work ok with other .DNGs, but if it came from Silverfast only a couple of them are there.

I'm using Photoshop 2026 on a Mac running OS14 Sonoma. Any ideas what's going on and how I can fix it?

Thanks!
