Mrk vs aupreset files?

Hi all, I’m new to Mirack and using it on Mac Catalina and in Logic 10.6

I’m trying to use presets that I created in the standalone app as presets in the Logic au instrument. But I noticed that standalone apps are .mrk files while the au instrument files are .aupreset. I tried copying .mrk files to au presets folder in Logic, but they are not visible when I try to load them, and changing the file extension doesn’t help.

Is there a way to reuse the standalone presets in the Logic au instrument?

PS I’d rather create presets in the standalone, because the Logic au instrument window is a bit difficult to use (hard to maintain full view on the rack elements)
