Symbol bounding box

I created a re-usable button symbol which animates a line where I can put text.
The bounding box is quite large so if I have a number of these buttons they overlap and only the top one works. I tried resizing the bounding box but it moves the symbol elements outside the area.
Ideally I just want the bounding box around the round circle with the plus46%20am 55%20am

SOLVED - I managed to solve it by resizing the bounding box and then opening the symbol and moving the elements
