Unable to organize the dynamic component label tag

I am working on SketchUp 2020 layout from last 1/2 year. After updating the Sketchup 2020 to 2021 pro. I am facing the problem in labelling and adjusting the dynamic component tags, whenever I try to adjust or stretch the tag it move along with arrow & remain same. After this when I re-install the SketchUp 2020 nothing change & issue remain same. I am attaching the video please help me to resolve this issue asap

@DaveR please help me out in this.

What is it you want to do? Change the size of the text box? If so, double click on the leader to open the label for editing and then resize the box.
