I am running into an issue when trying to process calibration images with Maxim DL v5.24 (cant afford the new version just yet). When i try to process Flats taken in Maxim DL it says it cannot find any images that apply even though i have correctly specified them and the header window for them appears to be correct. Bias and Dark frames apply correctly but not flats. What could i be doing wrong? What do you need from me to be able to answer this question? Everything else works great but not being able to apply the flats has made my images not turn out as stellar as i would like (Pun Intended).
