what is this red & blue circle? can't resize with red box anymore

[stiff mango]

Clicking away and then back on the deformer should help. You're currently selecting the red dot there which you can adjust by dragging

[old peak]

that removed the circles, but the red bounding box (terminology?) isn't back?

for clarification im trying to get this red box's visibility back

i've tried to click this in the edit menu, and it doesn't bring the bounding box back
