Hi @ExecutiveD15 ,
The only way to remove information from multiple contacts at once is to upload an excel file - however, in order for the existing fields to be replaced, there would have to be something else in those fields. As a workaround, I suggest uploading an excel file with just a "-" or a "." in those fields which will replace the information that's already in there.
I have tagged a feature request to clear out contact fields on your account, and I will be sure to have our engineering team reach back out with any updates we have on this.
