This all has to do with the "natural length" of a number
and how these numbers are converted to strings. It can be
a mess. :-)

My guess is that one of your numbers changed from an
integer to a float, and it is that number you are using
in your strings.

My suggestion would be to use a program like NUMBER_FORMATTER,
which takes some of the mystery out of what you are going
to end up with. Or, alternatively, you can convert your numbers to
strings with the STRING function and the proper FORMAT
keyword. (Good luck!)
