Looks like you have a warped heel which is not at all uncommon in the older razors...You can normally see the warp if you sight down toward the heel with the razor held up in front of your nose...
Here is the thing, if the razor actually has a warp then trying to grind off steel to compensate is a waste of time so look to confirm it before you start doing anything..
If the razor is straight through the heel and tang and spine then the "warp" is mis-honing and possibly can be corrected ...

This all comes down to what you see, not what I think from 5000 miles away..

I do know that 1 layer of tape and some Rocking x strokes mixed with some 45 degree heel forward stokes will get you to a clean sharp bevel, but they will not fix a warp
