As a relative newbie I've now had it with either Brother's Scan'n'cut software OR with SCAL5 OR with myself

I have been practicing for almost a year and literally every design I made with SCAL5 and sent (.fcm) to CanvasWorkspace (CW), I had to re-do in CW because not one single plane was closed for cutting. So I wasn't able to send anything to the SNC. Is this a problem that more people (have) experience(d) or did I miss something / do something wrong? For instance: the biggest problem was the impossibility of cutting an embedded plane in a bigger plane. I could cutout a big circle, but I couldn't cut the smaller circle inside, so the letter "O" was not possible.....
Now finally I'm looking for your help, because I'm not smart enough to solve it myself

Does someone recognise the problem and does she or he found a workaround?
Please let me know, because I love designing, cutting and making stuff to make people happy, but now it takes way to much of my time

I would love to hear from you!
