BUG: SPI3 respone data byte 0

[FMode]

I have a curious bug in App-IOIO0400:
In SPI respones in data byte 0 (the first byte send to Android) Bit5 is copied to Bit4.
This only happens in SPI module 3(!)

I can not debug - no pickit3 available.
I can only tell that the problem exists in "void SPITasks()" after line "ByteQueuePeekMax(q, msg.args.spi_data.size + 1, &data1, &size1, &data2, &size2);" Because I copied first byte to second byte and compiled firmware.
