Contact Manager disabled due to User Management

I have a newly installed FreePBX system - 10.13.66-15

I’m having an issue with module admin in that
Contact Manager is disabled due to "User Management module version 13.0.70 or higher is required, you have 13.0.68"
However when checking for updates, the latest version is 13.0.68 and there is no option to upgrade.
This is running on the stable track.

Phone Apps can also not be installed due to the missing Contact Manager requirement.

I have purchased Sangoma phones for this PBX and so I am assuming that I can use the Phone Apps module as well.

Any thoughts?

Thanks, that appears to have fixed the issue.
I did try searching both forums and bug tracker for the issue but couldn’t find it.

Why is this happening and can it be prevented in the future?
