Text is misaligned on different sized phone screens.

Hello, I am not sure if this is even an issue that can be solved, but as somebody who is using Squarespace for a portfolio to show my design work this is extremely concerning. I have aligned my text in both desktop and mobile mode, however, it seems on certain iPad screens and mobile screens some of the text is not realigning properly and some of the text is looking like the photo below. It is overlapping or two lines of text are right on top of each other. However other text realigns perfectly and has perfect spacing.

This is happening in several of my projects is there any way to make sure this doesn't happen? I use this portfolio when I apply for jobs so to see this from an employer's point of view it looks very unprofessional, especially for a designer. If not I will have to use a different website which I do not want to do! I hope somebody can help me find a fix. Thank you. 

@Ziggy Thank you! I realized I did have some text boxes overlapping! I appreciate you taking the time to help me find a solution.
