Trying to "sharpen" a razor with a leather strop could be an exercise in futility especially if the bevel is incomplete. The razor should be sharp before it goes to the strop.
Really hard to imagine what's happening without seeing the razor but if you want to fix it yourself I suggest lottsa research. Start here Straight Razor Place Wiki
Best thing you could do is get someone to hone it for you or buy another razor that is shave ready. It takes time to learn honing & having a 2nd backup razor that works will give you time to practice.
