I've seen something similar. It was when I first started using a straight and when stropping I would drag on the edge with to much pressure. I would try lightening your pressure some and make sure razor stays on the strop. Same goes with honing. Keep the pressure low when finishing a razor. I found that if I use too much pressure when finishing it will create a very thin edge that will fold really easy. If stropping doesn't fix it might have to goe back to the stones. Hopefully its not to bad where it needs more work since you only have an 8k as your lowest stone.
