I have Dolphin Version 20.12.2 installed.

I want to have a column which shows me the date of the pictures, when they have been taken (EXIF info from the picture).
I can add the column to dolphin, but for the picturedate it shows nothing.

When I mark the picture, the Detail view on the sidebar finds this EXIF info.

Can somebody tell me what I can try to get this issue solved?

Many thanks!
