I set up an offline event (S397 GTE at VIR, 60 min practice, 15 min race (if this is relevant, the cars were a skin-pack mod a league I race in uses)), which I completed. I then exited single player and went into an online Tatuus T318 practice server at Spa. I clicked the "Setups" button and "Show Only Relevant" was ticked, but all I could see were the setups I had used with the C8.R at VIR (see attached screenshot). This was with the latest non-RC release (the EXE says 1.1.2.5).
I have these kind of problems too. But there are so many more serious bugs in this game. These kind of little bugs just ruin the user experience but luckily didn't affect racing itself.
