Ever heard of synonyms ?

'Public' is a synonym for 'guest ok'
You have turned off guest access, then turned it back on again, last
one wins.

Are the shares being saved/owned by '%U'
This share (unless you missed a line) is read only.

Provided the file/folder ownership is correct, it should work, but I
cannot be sure if this is correct because you have made the mistake
that nearly everybody makes, you only posted part of your smb.conf, I
do not have a clue how you are running Samba because of this ;-)
