Hello,
In AGOL Mapviewer I have displayed my point feature map. For the selected point feature the zipcode (ShippingZI) is in string format in the attribute table as "02453", in the Fields list it's a string "abc" type, I have no option to assign decimal places in the Formatting panel BUT in the popup it displays as a 6 decimal place number 2453.000000. There is no arcade expression in play here either.

I have no idea how this is possible. Any help would be appreciated and sorry for the horrible graphic. It likely grabs attention but not a good thing in this case 🙄. Data is a little sensitive and can't be posted.
Thanks in advance,
GR
