Description Visual Editor (product category) disappear after removing rankmath

Hi, my visual editor tool bar for product category description disappear after i removed your plugin. At first, I didn’t know what’s the issue as the toolbar (where you can add image, heading, bold text, permalink) above the description box just suddenly gone. Then, i realized i removed your plugin that day, so i went back and install it. The visual editor appears again!

Why is this happening? Please help.
