Filter Gallery Available But not Working
I am trying to learn the Photograph-to-Watercolor process. I seem to have full access to the Filter Gallery, but I don't see any "Preview" in the Gallery, and when I click "ok", nothing happens. (My photo is not changed, and no "Filter Gallery" Smart Filter appears under my "Smart Object". Everything works perfectly under the "Filter" Menu (Guassian blur, oil paint, etc). It is only the Filter Gallery that appears completely disconnected/disabled. I have checked the basic issues, My photo is 8-bit 5 bit, RGB, Pixelated, and Converted to a Smart Object. I updated PS, and restarted my Computer. Can anyone help me solve my problem? Thank you for your time in advance!
[Edit from moderator: changed "5 bit" to "8-bit"]
