Ok, I understand what the pattern is now, I was the one in the wrong. In the text on the top it isn't very clear what the "Correct configuration" is, I had to read it a couple of times to actually understand that it was the pattern in the first level.
Yeahh I realized that, I actually edited the text to "valid rectangle" just now after rereading your comments but it was too late to reupload. That definitely could be a lot clearer, it kinda suggests that I hardcoded in solutions and expected you to guess until you found them 😅 Thank you for keeping an open mind and trying it again, and I'm sorry for the poor wording!
