Outside of print show interior floors
Sorry for the poor subject/title...
The imge below is a typical example. Whenever the print has an internal "floor" there is a ridge shown on the outside. I don't have any idea of what is causing it and therefore what I should consider changing. 
Apologies if I am leaving out any critical information. Below is the INI file from
C:\Users\Me\AppData\Roaming\PrusaSlicer\filament\Generic PLA @CREALITY - Copy.ini
I hope that highlights something that I am doing wrong.
Thank you for your suggestions,
Henry

Search the forum for "bulge" (also sometimes misspelled as buldge). Dozens of pages of discussion and many suggestions, but no universally applicable solution

Perfect - thank you.
Now I know what to search for. Hopefully the answer isn't "throw the machine away and start over"
