Dublicate characters in PaddleOCR

Question

I am trying to detect number plate of vehicles using paddleOCR. In the output, some characters are being repeated. For example:

Orignal Number: HP829 PaddleOCR Output: HHP8229

Orignal Number: PB6279 PaddleOCR Output: PB662799

I am using base PaddleOCR model and have not trained it. But when i upload the same number plate image to paddleOCR site, I get the correct results.

Thanks
