Problem/Bug worldguard problems

since i started making my own server i am having problems with the worldguard plugin. when i configuared the plugin and i started testing with an alt i couldnt access to chests and breaking block/building. the thing is that i dont know what causes it in worldguard. i tested this in the askyblock plugin with players having these perms:
- worldguard.stack
- worldguard.chest-protection.override
- worldguard.override.chest-protection
i have in the __global__ region these flags: passthrought allow build allow chest-access allow block-place allow block-break allow pvp deny pistons allow use allow damage-animals allow mob-damage allow mob-spawning allow greeting allow...

any ideas what could have caused these build problems?
for the members i have set the groups of my pex file

 

i have set that to 0 some time before, it was 16 standard but has it to do that i have to set my spawn at coördinat place?

 

@timtower still i tried to build alot far away from spawn but without /op they cant break blocks
here is a list of my server plugins: https://pastebin.com/vePFuV6g

 

I know world guard pretty well and haveing it far away from spawn if not working is not good, you might have a plugin interfereing with world guard, but I suggest you make sure that player has the permissions to make world guard regions and that they are the owner of the region.

 

i have it fixed, due to not giving them permissions of flags
