Barcode scanner is not working as expected

I am using POYNT SDK -

 compile 'co.poynt.api:android-api-model:1.2.108@jar'
 compile 'co.poynt.android.sdk:poynt-sdk:1.2.27@aar'

When I read a barcode using scanner I am getting different codes for the same barcode . This issue happens quite frequently .

Few examples are as follows -

example1- 0197928065670180
example2- 8482890498983

Image has the barcode and the number is scanners output for the barcode .

As well I am using the barcodes which Poynt claim to support -

The following formats should be supported:
 EAN8 
 UPCE 
 ISBN10 
 UPCA 
 EAN13 
 ISBN13 
 I25 
 DATABAR 
 DATABAR_EXP 
 CODABAR 
 CODE39 
 QRCODE 
 CODE93 
 CODE128 

Note - We are using library provided by Poynt for barcode reader .
