EXTRACTING NUMBER - am I doing something wrong?

[hunaism]

Ok, so I have an OCR function implemented and OCR_Text column (LongText). Sample data like this:

I would like to extract digits out of the OCR_Text and store it as Number so I’m doing following tests with virtual columns:
Column “temp3” =EXTRACT(“NUMBERS”, [OCR_Text])
Column “temp4” =EXTRACTNUMBERS([OCR_Text])
the results are as follows:

The funny thing I noticed that EXTRACT(“NUMBERS”, TRIM(SUBSTITUTE([OCR_Text], " ", “”))) returns no List/Value
