[14.21] circuit network- minor display bug

[Gnorok]

During one session, entities of the circuit network lost the ability to display the number "3". E.g. when I entered the constant "37000", it showed "7k", but worked correct with "37k". Restarting factorio solved the problem.

Ill move this to magic, if you this happens again or you discover a way to reproduce it let us know.
