Can't check "Constrain features by mask"

[$.H0LM3S]

Hello everyone!

After masking the background, before alignment, I wanted to check the box “Constrain features by mask”. But that isn’t possible. Can anyone say why and how I can fix it?

Cheers!

Hello $.H0LM3S,

Please check that the masks are present in the active chunk, you can press Show Masks button on the Photos pane toolbar and check the image thumbnails.
