Google Vision OCR randomly not detecting negative signs

Hi All,

I am trying to extract values from a financial document using Google Vision OCR and for an unknown reason the negative sign is randomly not recognized by Google Vision OCR. 

I've tried changing boundary boxes, contrasting, gray scaling and light touch gaussian blurs to make it stand out but I don't seem to make any progress.

Can anybody please help with some advice or fixes for this etc.
