I'm using this Fintie Kindle Voyage Slim Fit Folio for my Voyage:

I haven't had any issues until yesterday. I was sitting down at a table and put my Kindle down flat on the table with the cover all the way folded back so that the Kindle was sitting on top of it. The kindle then started to go into sleep mode/wake up/go into sleep mode again etc. I had to pick it up and move the cover away from the back. I guess it detected the magnet from the other side. I tried to replicate that later on in the day but it didn't seem to happen again.
What gives? Is there a special circumstance of laying my Kindle flat down with the cover like that? Metal table at Starbucks? Some other factor? Anyone experience this with their covers?
