Re-sizing in breakpoints not working

Hi Anastasia! I am not exactly sure how to make sure the text is a specific pixel size, i tried to make sure that it was responsive (the text should resize with the screen so I am not sure whats going on) I did try to add a bigger breaking point and then got rid of it, so maybe thats the issue? I am having the same issue in multiple sections. here is the link https://anaordas1999.editorx.io/prietodesigns/umbrella-centre-project
