A 10.5" barrel makes a little less blowback strength so the 22 bolt isnt coming back far enough
to recock the hammer and lock back. or the chamber adapter fits real loose in the barrel and lets some of the blowback power escape. Stronger ammo or a little tuning to the recoil spring or a little bend in the hammer spring will fixit

You could put a can on it
 or use stringers!!  in the SBR, then you'll have function!!
The spring tuning tips should help you out pretty good. If you are using this insert on different length barreled uppers....you may just want to look at a reduced power hammer spring, if it will make your ammo go bang. In addition.....Wolff makes a 10/22 recoil spring (std power) that will probably work well for you too. I hate cutting springs, but for about 10 bucks, you can have a replacable spring from Wolff.
