Excel keeps resending spreadsheet link to users

I created an excel sheet in Microsoft 365. I invited 4 users to the spreadsheet. For some reason it keeps resending the invite link to all 4 users every 30-40 minutes and I can't make it stop. It's blowing up their emails and they're getting frustrated. Please help me make it stop! It's resending the invite link even when no one is working or updating the file. I added a screenshot below for reference.

How I shared the spreadsheet:

Share>Share>Add a name, group or email> entered users names one by one and added them>Send
