OCRExtractRelative has different output on similar pictures with different number

Hello,

I have the following issue which already wasted me 2 days.

Why this tool can print me the result from Screenshot_1 but cannot print me the result from Screenshot_2 , and many more?

Screenshot_1
Screenshot_2

Its ridiculous. The second screenshot is unreadable for the UIvision. #desktopversion

First, I recommend to make the pink box larger, a bit more white space around the text usually helps.

Second, the key issue is single digit/number ocr, that is very tricky. Did you try with both, OCR engine 1 and 2? Usually Engine2 works better for this use case.
