settings help: filament is retracting all of the way out of hotend assembly?

[Snowfox222 0]

im running a davinci pro 3in1, and yes i know thats my first problem. ive been running cura for a few months now and have had little to no problems until this. last week i clogged my nozzle to the point of needing  to disassemble my entire hotend three times in one day. on closer inspection i noticed that instead of my usual 6.5mm retraction, it was pulling the filament out of the hotend and partially into the bowden tube before running it back in again. no bueno.  i tried adjusting my retraction to 6mm on the off chance the decimal place wasnt registering, but to no avail. i also tried just turning retractions off and this worked... sort of. it stopped any retractions except for inbetween layers, which again takes a left turn at Albuquerque and into into low earth orbit with my filament.  

 

is there another setting not labeled as retraction that "retracts" so to speak? is this an issue that might be resolved by a reinstall of cura? ive got nothing on this one guys, totally shooting in the dark.
