The ticking area in my realms world not working

I’d set the usual commands /tickingarea add circle ~ ~ ~ spawn or spawns cords which are [222 72 489|tel:222 72 489]. The screen will say the tickingarea is placed. I’d grab tnt from creative because I set a command block that will clear all tnt. 

then it wouldn’t work and the tnt wouldn’t disappear and ik the command block is working because when I tp to the area where the command block is, it automatically works. What should happen is that when I set the ticking area the command block should work in that area. How do I get rid of this bug?
