New Install of Acrobat Reader (May 2022) doesn't display all signatures - appears to be missing font

[Skorp 62]

I have a new install of Acrobat Reader (May 2022) and it doesn't display all signatures - it appears to be missing fonts or something. I have recieved some notifications about fonts - but this issue never corrects itself. Is there a package I can install to fix this?

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Acrobat Reader forum so that proper help can be offered.
