If the content is 50Hz and your TV supports 60Hz but not 50Hz ; then
it will switch to 60Hz.
If it uses 24Hz, it's because your content is 24Hz... simple as that.
When watching new content and you have the automatic rate selection
activated; whatever refresh rates your TV was set to is irrelevant and
doesn't have an impact whatsoever on how the rate is going to be
selected.
When a refresh rate isn't available, it uses the highest one available
; e.g. 60Hz
You can try it by first watching 60Hz content ; then go and watch your
"50Hz" content you see that it won't stay at 60Hz (if you say it was
selecting 24Hz before)
Aside, I would be extremely surprised if your TV supported 60Hz an
24Hz but not 50Hz...

Why?
How does having a 24Hz refresh rate or 60Hz refresh rate makes any
difference for displaying a static content like a menu ?
