Here’s my problem:  
Application reads PLC data that is stored as integer. PLC value assumes an implied decimal.  
We want to display and treat the value within ignition as a float.

In the tag definition: Tag is declared as float and source is declared as long.  
Input is scaled (0:1000 -\> 0:100) to account for the implied decimal.  
Tag metadata specifies one fixed decimal point. (###.0)

On the screen:  
Numeric Text Field  
Number type = float  
Tag value is assigned to Value (float)  
Format = ###.0

There are 5 of these tags. Two of them display one decimal (as configured). The other three display no decimal. Ever.  
I have copied and replaced all combinations of tag and numeric field. No change in displayed decimals.

Any insight?

Two of them don't display `#.0`? Or two of them always show `#.0` (zero in decimal place), even when they should show `#.1` or some other decimal?
