Expandable Card Animation Open Issue

I have changed the Expandable Card height to 100% and disabled animations but I am facing a little problem.

Upon initial opening of the Card the Animation is displayed and it thinks the card is still 300px and animate it shortly smaller and makes it bigger again later. Its just a little and short but noticeable

any idea how to fix that?

Would be good to see an example

I am sorry i already fixed it! it was another animation which i added custom, which was the bad boy
