Module Update Mismatch

Currently running through a batch of required module updates and I have a few that are all dependent on each other with a key module requiring; Missing Requirements: * EndPoint Manager module version 16.0.79.6 or higher is required, you have 16.0.77.1 However Endpoint Manager is showing as 16.0.77.1 and being up to date. Not sure how I go about getting the later version? I am running FPBX v16 and have a valid EPM licence on the system
