From tutorial "Play an Image Sequence": bugged Frame Rate Override?!

Hi there!

I followed this tutorial in order to be able to play an image sequence:
https://docs.unrealengine.com/5.3/en-US/play-an-image-sequence-in-unreal-engine/

It works fine with the default 24fps. But i want to use 1fps or even a lower fps.
There is a function to override the fps:
image

Sadly it doesn’t work. Everything below 24fps is not working:
image

Is this a bugg or am i doing something wrong?
Thank you!

Using UE 5.3.2

Hmm, funny thing is, when i play the sequence in the MediaPlayer and choose “Reverse” it works as should be!
Is there any option to set up the Image Sequnce in reverse?
