Casting the value to int seems to resolve the issue.
Line 859: $rendered_values[] = number_format($new_value, $custom_delimiters[0] ?? 0, $custom_delimiters[1] ?? '.', $custom_delimiters[2] ?? '');
Potential fix: $rendered_values[] = number_format($new_value, (int) $custom_delimiters[0] ?? 0, $custom_delimiters[1] ?? '.', $custom_delimiters[2] ?? '');
toddses → created an issue.
I think this is resolved! Added a title property for display purposes, as modifying the casing on the name itself causes ID mismatch issues.
At Pittsburgh and taking a look at this one.
