CRC Problems with NRF24L01P

Hi,

I' ve got strange problem with two NRF24L01P comunications.
Sometimes i've got corrupted data. I try to set CRC to 8bits or 16 bits but it doesn't change any thing.
For my test, i send always same message :
1 1 ab01 1234 11.100000381469727 22.200000762939453 33.29999923706055
1 1 ab01 1234 11.100000381469727 22.200000762939453 33.29999923706055

1 1 ab01 1234 11.100000381469727 22.200000762939453 33.29999923706055

but sometimes i received the bold message.

Can you help me to find a solution. I don't understand why i received it when CRC is activated.

thanks for your help.
