Astroart Flat -darks size

[boeingses]

Hi folks, I use astroart for my image stacking, but i always get the following message during the stacking process: "F.Darks are not the same size, Continue anyway?". I dont use bias, only darks, flats and flat-darks. I have no clue why this is happening, and it seems that it is preventing the flat-darks to be discounted from the flats.

Hi, only things I can suggest to check; binning as astroart usually reverts to 2x2 went you first connect your camera making this an easy mistake, changes in your camera driver... with QHY you can include the overscan area this effects the frame size but can be cropped if necessary. 

Do the F. Darks frames have the same xy pixel counts as the Flat frames?

Go into Preview and check the raster size.
