3 number read brings an extra symbol in the output

[z20leh]

Hallo,
i use  ubuntu-22.04.2-desktop-amd64
tesseract 4.1.1  leptonica-1.82.0

i have small picutres with only 3 numbers.
For example:
1,02
in the outputfile of tessercat is an extra symbol.
See the picture attached.
Is this a bug? Is it possible to create a output without that symbol?

Thank you.
