Error "document not saved" when want to save Word/Excel files on NAS server

Question

Hello everybody!
I have a NAS server (QNAP storage).I want to have some folders with these permissions : 
1.nobody can create or delete folders in first parent folders (blue folder and red folders )
2.everybody can create/save folders,docs... in it. (Black folders)
when I set permission like picture below,people can not save documents in Excel or Word format in folders ( I have this problem just for Word and Excel).they face with errors : document not saved / access denied,contact your administrator.
special permission for blue folder (domain users) 
(include inheritable permission) and (replace all child subfolders...) are unchecked.
traverse / execute files
List folders/ read data
Read attribiutes
Read extended attribiutes
Read permission
special permission for red folder :
(include inheritable permission) and (replace all child subfolders...) are unchecked.
traverse / execute files
List folders/ read data
Read attribiutes
Read extended attribiutes
create files / write data
create folders / append data
write attributes
write extended attributes
delete subfolders
delete
Read permission
special permission for black folder :
these folders inherit permissions from parents.
(include inheritable permission is checked.
(replace all child subfolders...) is unchecked.
when I uncheck "delete" permission in red folders and save it,"modify" permission in main permission will uncheck,too.I dont know why?in this situation,people can save docs, but they can rename/delete folders,too ( I dont want they delete
or rename parent folders).
what I must do?
regards,

Hi.
How are the rights configured to be inherited? Could you do a "icacls <folder>" on each level and post it back.
Also worth considering is that this is a Linux Samba system, so it might not work as a regular windows system.
