It does not seem to be exactly the same problem, my menu shows the correct icons for all applications for all other users on this machine with the same language (fr), this is only affecting one user, only in "control center", any idea on how to edit the "path/link"...or fix this ugly picture 
?
In fact, since release 20, these 2 menu shouldn't be part of de control center, it comes from a restore of the release 18 for that user, do you think I should remove and re-install mate-control-center ? Or is there a config file I could remove / edit / reset /copy ?
It should look like this picture
mate-control-center
