I must be missing something very simple, but I have a field that for 1 of 3 values does not display the value correctly. The first field in a portal is supposed to display FULLNAME. This field is the concatenation of 2 values from linked tables. For the first 2 rows it works. For the 3rd row it displays 9.9077e+09. If I click the field, it shows the correct value, but as soon as I leave the field it returns to 9.9077e+09. I have expanded the size of the field way beyond the value to be displayed, but cannot get it to render correctly.
I have attached screenshots of the layout, showing the way the field is displayed.
