Zoho Creator Sending Additional Emails to Select Database Member. Why!?

Zoho Creator Sending Additional Emails to Select Database Member. Why!?

We use a script that sends an email out to each member in our client database IF 1) it is a new member OR 2) if we physically select a checkbox that instructs the script to email an update status to a member. (Be aware that the update select button mentioned is reset after every use, thus, it must be physically reset with each update.) However, as of yesterday, indeed, each member updated receives the email, but in addition, and most incorrectly, one particular member, newly added as of yesterday, gets an email for every member that receives an update. Two-fer! WHA!? In other words, if I update any record, Zoho Creator sends a second email, but to a singular member out of hundreds.

This has never occurred previously. No scripting has been changed by our team (check versions date). I cannot account for this. Can you!?
