TTF export changing curves

Design
1

Hello, I’m experiencing a trouble that I’m not sure if it has a smart solution.
When I export my font in ttf, as expected, Glyphs add some points to the curves,
but doing that, some curves are moving, and creating kinks.

When I export as otf, my curves go perfect.

I’m choosing to export ttf because the hinting makes it look way better.

Now, my questions:
1 - Is there a smart way to correct this ttf export?
2 - If not, is the best idea for me to create the extra nodes on the curves before I export the ttf?
3 - Am I clear? Can you understand my problem?

thanks

Can you send me some examples? And file with one or two of the glyphs would be good.
