All command blocks with new /execute format created before 1.19.50 update don't work

All command blocks with new /execute format that's created before 1.19.50 update doesn't work now.

command block with new /execute format in the video (Written before 1.19.50): /execute positioned 978 -59 1018 run testforblocks ~ ~ ~ ~ ~ ~ ~ ~-3
It somehow results error with "run" part and this shouldn't happen...
at least I can fix it when I write something random and update the command block and revert the change to original command block, as you can see in the video,
but this is extremely annoying bug as i wrote like 500+ command blocks with new format in 1.19.40

Note: It seems that command block with "Version 21~24" will result in error with new /execute format. I used my data editor to rewrite version "24" into "25" and the command block worked correctly.

(One at the top is a repeating command block which doesn't work since 1.19.50, it's version value is "24".
And other one is a repeating command block which I fixed using the method above, it's version value is "25")
