Animation can't work properly after close and open for 2nd time

Design help Animations & Interactions
1

Hi there,

I created a animation for FAQ ( in Learn page ), and the first time I click plus sign to open and close, it works. But then when I click 3rd time, the animation began to work in wrong.

Can anyone help? I am a new designer in webflow and interactions are challenging for me.

Many many thanks!
