Lower user levels can't see superior level changes

Lower user levels can't see superior level changes

We’ve been facing some difficulties, because every time that a superior level introduces some changes or create new fields, the lower levels are not able to see them or use them, even after that accesses are given to them.

For other others, the lower level users keep having the same information they had before the changes, and they can’t use the new or modify fields created by a superior level.

We tried to upgrade a lower user, giving him the administrator (for example) permissions, and in this case he can see and use the changes created by the administrator. But, once we cut him these permissions, he is not able to see them or use them anymore.

Can you help?
