Superelevation Don't Work in some Tracks

[FS.E652 091]

Hi all, I have a problem with superelevation in Open Rails.
I state that I use the recent Monogame version, therefore, let's go to the point ..

I recently duplicated an existing scenario to rebuild the TDB back to the 1990s.
therefore I practically created a new route with the TSRE5, after which I inserted the World and Tiles files of the previous scenario, and then proceeded to a manual rebuild of the TDB.
After a testing, in terms of stability it's perfect, but I noticed a little problem..
The superelevation in many points, has practically deactivated, but, It works in the previous version of the scenario.
Also i've noticed that there are some trackprofiles in some curves but ther are flat, with no superelevation, sounds like a big problem..

What could this problem be caused by? and above all, can TSRE5 fix this?

thank you in advance for the replies
