New Samba user creating folder missing write attribute

smb.conf:

(Client-Billing)
   path=/server/Client-Billing
   force group = company
   guest ok = no
   valid users = @company
   writeable = yes
   create mode = 0775
   directory mode = 2775

Several users use this folder without issue. Created a new user but when a folder is created by this user, Samba is not setting the proper “write” flag on the folder; therefore, no one can place files inside it. I’ve deleted the user and tried again. Created a new user, but getting same results (all of the sudden). This .cnf has not been touched in over three years. Any suggestions or help would greatly be appreciated.enter image description here
