Photoshop 21.0.2 doesn't use selected scratch disc

Question

Hello,
 
I have MacBook Pro 2017 with 128GB SSD and external WD My Passport 256GB with over 190GB of free space.
 
When I go to Preferences - Scratch Discs in Photoshop (please see screenshot below) it shows my local SSD's free space on both discs, which is incorrect and it apparently use only the local SSD even if only the external one is checked.
 
Thanks in advance for any help, it is really urgent as I can't get my work done surrounded by so many deadlines!
 
EDIT: Photoshop version is 21.0.2

Hi there,

We are sorry about the experience with Photoshop.

Would you mind checking the format of your WD my passport connected to the computer? For the drive to work correctly as Scratch disk with Photoshop on macOS, the drive should be in macOS extended file format. If the drive is not in the specified format, Photoshop would not be able to detect it. (Most drives are in NTFS format out of the box which is basically a Windows file system format)

If the drive is in the correct format, you can try resetting the preferences of Photoshop using the steps mentioned here: https://helpx.adobe.com/in/photoshop/using/preferences.html

You may want to backup your actions, brushes, etc. before resetting the preferences. Please check: https://helpx.adobe.com/in/photoshop/using/preset-migration.html
