I have command blocks for restricted items in creative like this

"clear @a[name=!ADMINUSERNAME,m=1] apple"

and I have a bunch of these. All of them were working 100% perfectly and removing items immediately before around 3 o'clock today, all of a sudden some of them are working, and others are not. Attempting to destroy the command block and recreate it does not help. Moving to a new location further away and placing the exact same command works, but my area (which is set up as a tickingarea) for all my commands is intermittently not working.

I have disabled command blocks and re enable them, I have reset the ticking area... what happened at 3 o clock today? My realm is being completely thrown out of wack because of this!? Not seeming worth that $7.99 atm.
