I noticing something a bit "odd" this morning when stropping.

I have a 3" SRD red latigo strop. It appears to be perfectly flat and untwisted, and the blade looks to be staying nice and even, flt during my stroke. But, I've noticed scrapes or scratches on the very edges of the strop when I finished up. Not nicks, and no performance issues with the blade. Anyone else had this happen? Anything to worry about/ adjust?
