Figures labels for our method is hidden after I resize the font size.

Hi, I am submitting a paper to SCIE 1 journal which uses double-anonymous peer review process. The submission status now is "Under Review"

I realized that 4 Figures labels for our method is hidden after I resize the font size. I only realized it after I share it to my classmate. Upon which I double checked the PDF, the figures labels are hidden for our method.

I am thinking to email the Editor because although you can deduce which line is our method, I was thinking to myself "wait, which method is this line". So I can only imagine that this will confuse the reviewers.

Should I email the Editor or wait for the first revision?

Note: I am not sure about "Under Review". But I imagine the review stage has started.
