Removing commas in text after API call


I have imported text from an external source and when it is displayed it shows a “,” before the start of the text and I can’t work out how to get rid of it. It shows on all text boxes. Strangely at one point it completely disappeared without me doing anything for a day or so but then it’s come back but with 2 “,”’s before each text.
I am importing text from Airtable by entering an API call for the text box it is viewed through on the design.
Can anyone advise how to remove it?
