Sounds to me like one of your sensors is hogging the available bandwidth. 100 mS between broadcasts may be too short, depending on your baud rate and packet length. What is you baud rate? It looks like 1.2kbaud which is ~ 1.2 bit per mS.
A basic SimpliciTI packet is 12+ bytes of network data + app payload + 4 sync and 4 preamble. That is at least 160+ bits. at 1.2k baud it would take 133 mSec just to transmit the overhead data and no payload. So try setting your EDs to report every 500 mS or increase the data rate.
