I think this is a bug. When I open a Pentax RWA-file (*.PEF) in Affinity-Photo V2, I get a blank sheet on my screen (see sreenshot 1). When I change the preset in the develop-studio on the right side, the picture appears and I can proceed (see sreenshot 2). With V2 on my I-Pad there is no problem like this.
In V1 I can open the same file and develop it, without any problems. I'm glad not to have deleet V1 from my Computer. I'M working with Mac OS 12.6.1
Hope you can fix this as well as the problem many users have, when they want to migrate their presets von V1 to V2.
Thank you
