My get-help about_comments... aren't there

I seem to be missing some help files. I am running PowerShell 5.0 (v1???) and I have run update-help numerous times. I even tried identifying the module that would provide this help and tried importing and installing various modules. All to no avail.
Under certain about_ topics there simply is not a helpfile item in the second column.

When I try to do tab completion on get-help about_ it gets stuck on the first one and will not iterate through even the other few that are available.

Here is also what happens:

It’s possible that you have a module with a bad Help file, which can bork up the rest of the system. Look for any non-Microsoft modules and consider temporarily removing their help files, one at a time, to see if you can find a bad one.

Is there a way to just remove the other module’s help files without removing each other module itself?

Thanks,
