@mapLeafYgh,
I couldn't reproduce the issue in the following demos:
https://files.dhtmlx.com/30d/8a4cf4fbcdb7004218ded679c256f1e1/vue3-gpl.zip

https://files.dhtmlx.com/30d/febe11dcc7f1627a53571342413dc613/vue3-trial.zip

It is hard to suggest what might be wrong as I don't see your code. Please share a ready demo so that I can reproduce the issue locally.
