Exhibitions and Street Scene Race progression stopped

I am stuck at 68/70 exhibitions. I finished Goliath 2 days ago. I am definitely missing that drag race which will unlock in Winter seasson, anyway I am really not sure about the last one:( Anyone any hint?

Further in street scene race I am stucked at 20/21 - is there any race hidden in Autumn or Winter seasson? So far I have passed only through Spring Summer seasson.

On my map I have all events with trophies and description completed.

This could be my first game I could fully 100% complete but I got stuck here anyway still have some activites to go, including DLCs. Roads and signs already completed.

Thank you.
