Different results with tesseract in one image

Question

Hi, I'm trying to create an image.

this is the original image after pre-processing (skipping part of the pre-processing, as it is not related to my question, but will be shared if someone needs it)

I have this image

when i try to execute this image using tesseract

I get the result as

HN'

2809

however, when I manually crop half the image in Photoshop

I get

HN'

Z8

.

I wonder what's the difference between these two images, because instead of Z is assigned to 2 , and the other - Z .
