Now that you are having a go at it, see if you can share or upload your plan file you should get quicker more accurate answers

If i understand correctly, change setting shown in screen shot then rebuild foundation if i am wrong show me what you need in screen shot

Its all good don't worry but it still has a problem it must have been open in chief as the plan file has zero bytes size or maybe you attached the same file

I think you had the file open in chief when you zipped it, as the file has 1 Kb make sure you don't have it open in chief when compressing it, also it may end up being bigger than 14mb after zipping it so you may have to put it on google drive dropbox or other

I think you may have forgot to attach zip file

You need to share your .plan file not .layout
