Retraction is a complicated issue. there are several settings related to retraction. The one you care about is to try to prevent the filament from grinding. I have done prints with 500 Meters of retraction. In one print! That's a half kilometer! I have found that if the same piece of filament goes back and forth 10X through the feeder it is always fine but around 20X or 40X through the feeder and your print can fail.
Because of this there is a parameter that keeps you from retracting too much. I forget what it is called but something like "minimum extrusion before retraction" or "maximum retracts on same filament". Something like that. They have changed the name and I lost track.
There is *also* a parameter that prevents retraction if the gap that you have to pass over is smaller than a given distance. This is unrelated to your issue above but good to know about.
