Mask issue when overlapping

Hi everyone, having a really issue with Lunacy at the moment and it is kind of a massive problem that I could really use some help with.

I’ve got four symmetrical masks on top of each other and last week I could drag and drop images into each one individually without a problem. Went to do the same today but unfortunately no matter which mask I try to drop the image it always ends up on the top mask and doesn’t want to change the others without manually clicking the fills button. Have I changed a setting or has something gone completely wrong here?

Thank you ,

The issue should be completely fixed in the upcoming major release. You may also like to check up the alpha to be released within the next few days.
