200 fps proxies will be 240 fps

I am using version 24.6.1.

When I create proxy for 200 fps clips the proxy files will be 240 fps. 25, 50 and 100 fps clips keep same fps proxy clips. I have never experienced this before with 200 fps clips. The export version is without stutter (25 fps) so this problem is limited to the preview. Any thoughts?
