PI Vision no access some Sub-Element

Hi Everyone, I get problem about access Sub-Element from PI Vision.

Previously, I created element, attributes on AF-Database. everything is normal.

For now, i create some element. but i can't access this sub-element.

i checked security of element and i still good.

i don't know reason for this. hope for help.

thanks so much!
