Hi Jane,
Apologise for delay in response, i am not from Node.js and i am from java, i have difficulty in pointing our "wait" time you are referring in your post in any of the three screenshots you have shared.
In general, we do show wait time(ms) (not object.wait call) but this represents cpu or i/o wait time, see if this is the case in your case.
It is not clear from screenshot is there any further call graph , you can export call graph text completely using "export" option and attach to this, if query is specific to controller i will try to clarify at my earliest
