“Reason: Clean up your layers and names” – what does this mean?
Probably you should clean up your psd files 
My AI end EPS files is clean and therefore the question…do not understand this…
Probably it means, that you should name all the layers properly and also make sure there’s no confusion by using named folders and stuff.
just take another look on your file, maybe you find some “problems” you can improve.
good luck!
