Blank Pro tools session Icon in finder Mac

Long story short last week I had to re-instal my PT 11 on my system and all went well. I did however notice right away that all my session icons in folders were blank. They still open fine but they are blank in folder. meaning they don’t say pro tools any more. still have the .ptx on naming scheme. I did find that older PT 9 session displayed correctly. Has this happen to anyone? Can anyone help? Thanks
