Repeating Command Blocks set to Always Active stop working after updating them

After putting a command into a repeating command block set to always active, the command runs like it should. But, when updating the command, it stops working and does nothing. My solution is to ctrl-pick block the command block, break the original one, and place the new one back down. This only happens with always active command blocks as needs redstone ones work properly. If you change it while always active (it stops) and then you change it to needs redstone, then you power it, it runs the new command so when you change it back to always active it runs the new command but if you just flick it between always active and needs redstone, it's still broken. This also happened on the 1.21.30.23 preview.
