Raise/Lower Tracks function corrupts tracks.bin file

I've been upgrading all of the original KRS Euro routes (NY, OP, HS, SD) with the AP track textures, and need to raise the tracks a bit (usually +0.1000) to prevent terrain spills. This functionality of RW (found on the Route Building Tools\Check Routes or Scenarios\Raise or Lower Track button) used to work fine. But with the latest version of RW_Tools, 8.1.16, the use of this tool corrupts the tracks.bin file by moving buffer posts and, in some cases, causing tracks to disappear. See pics below by clicking on the thumbnails.
So I thought that perhaps the problem was with one of the recent Windows Updates; perhaps some .dll file was changed or omitted and this was the cause of the problem. What if I restored Win10 to the version I got when I joined that freebie Win10 download that MS offered 3 years ago (Windows 10 Pro Version 1607 OS Build 14393.0, to be precise). I still had that on a thumb drive, and the registry was being clogged anyway, so a refresh of the OS might get me a faster machine as well as fixing the Raise/Lower track problem.
Long story short, I did get a vastly quicker machine, but the Raise\Lower problem is still there. So I went back to the earlier full version of RW_Tools, v8.0.20, and tried that. Still no dice. I unfortunately ditched my earlier versions of RW_Tools, so do not have recourse to that option.
Anyone else have this problem? You can check for yourself by simply clicking on one of your routes on the "Check Routes or Scenarios" screen and select the Raise or Lower button, then choose a small amount to raise or lower. (BTW, the bug operates the same whether you raise OR lower.) Don't worry, Mike's program saves a copy of the route's tracks.bin file, so you can simply toss the modified one and revert to your original. If it does work for you, please let me know, and also know what OS and RW_Tools version you are using.
Thanks,
Dave

Paddington post-modification #1 What's this buffer post doing here?!

Paddington post-modification #2 Hey, where's my buffer post?!

Paddington post-modification #3 At least the post doesn't impede traffic or derail stock.
The situation out west in Oxford is even worse; buffer posts are the least of it! See below:
