No, Glide will see those as non-empty and will add new rows below.
Are these formulas that you copy/paste down as new rows are added?
If they are, you would be better off replacing them with arrayformulas. See below for more on that:
Even better would be to get rid of formulas in your Google Spreadsheet altogether, and do all calculations in Glide using computed columns. Whether or not that is the best idea depends on the purpose and use of your App.
