Slightly loose exhaust valves

So I'm going over my bike a little tonight and the exhaust valves are just out of spec on the loose side (2014 KX250F spec .17-.22mm) I'm at .23

Now I have a race this weekend and I've never shimmed valves before but don't want to miss the race. I'd hate to tear into it further and run into issues and not be able to get the bike back together for the weekend. How bad is it to run the bike as it is and deal with it next week when I have 2 weeks before another race?

And shouldn't the tolerances get tighter not looser? My last valve check I have them written down at .022.

Oddly enough there is a marking on the cam cap that says 23 in marker, maybe the engine builder set them at .023 and I mis measured last time?

Now I'm confused lol.

They will tighten up its fine if it starts and runs good. Just less valve lift
