Adding MIB files

Good morning, I don't have much expierence with MIB/OIDS. I am attempting to add the Cambium MIB files to our Dude Server running on the RB1100AHx4 "Dude Edition". It is adding it to the /files folder by default, however I am not able to see the MIBS in the Mib Module. Everytime I enter a Cambium OID the dude is showing "invalid oid" which I assume is because it doesnt know where to look for the Cambium Oids. What am I doing wrong? Anyone else having this issue or anyone have a solution for me?
