Data chopped off at ends with nRF24L01+

Hi,

I've successfully hooked up two nRF24L01+'s on two LPC micros. Upon startup using the nRF24L01P_Hello_World program, I see the setup parameters on both devices and I am able to communicate messages between them successfully, aside from one minor problem:

A lot of the messages have missing characters at the end of the string. For example, if I send the character array "Testing123", sometimes it shows up on the other device perfectly, other times it shows up as "Testing12" or "Testing1". When sending another packet, the rest of the characters from the previous packet sometimes show up. Are these missing characters sitting in the buffer?

I'd like to reliably transfer some data, so can someone please help me out with what may be causing this?

Thanks in advance.
