Why when creating a folder via CMS(Bitrix) acl can be set incorrectly?

Question

linux

Good afternoon! There is a problem, when creating a folder in the CMS(Bitrix) admin panel, the mask that is set on the folder is mask::rx , the full output of getfacl is given below. When creating a folder via mkdir on behalf of the user under which the web server is running, the rights are correct. The test-folder folder is created in the CMS admin panel.

# file: test-folder/
# owner: web-server
# group: web-server
user::rwx
user:web-server:rwx #effective:rx
user:webdev:rwx #effective:rx
group::rwx #effective: rx
mask::rx
other::rx
default:user::rwx
default:user:web-server:rwx
default:user:webdev:rwx
default:group::rwx
default:mask::rwx
default:other::rx

Thank you!

So, I figured it out, the fact is that the chmod command changes the mask when changing the rights to the group. Bitrix has a dbconn.php file, in which the value of the files created by default was 644, so the rx mask was in the created directories.
