QR code scanned with ECC M, but Binary Eye shows QR with ECC L

Binary Eye 1.59.0 for Android

I scanned QR code with ECC level M, this one:

Binary Eye decodes QR and shows QR that has different pattern; that QR is generated with ECC level L and I think that is a bug:

Scan again, Binary Eye confirms that it is QR with ECC L:

I updated Binary Eye to version 1.63.1 and the bug is fixed, the generated QR code has ECC level M. But it doesn't look like the scanned QR code, the pattern is different...

QR codes are different because those are generated with different mask pattern. Scanned QR code was generated with mask pattern "M-2", Binary Eye generated QR code with mask pattern "M-1". Is this a bug in Binary Eye? If this is not a bug, could be added an option to rotate between different mask patterns, to find detail about mask pattern?

Binary Eye can generate QR code too. There is an option to define ECC level (L, M, Q, H) but there is no option to define mask pattern, it looks like it is hard coded to type 1...
