log4FIX - Bug (maybe not within QuickfixJ)

At the end you see 4 market data snapshot messages from Hotspot.
If you put the into a file (copy and paste) and open it with log4FIX the repeating groups are cutted of.
This occurs sporadic and I have not idea why and when.
I need to evaluate if the same problem occurs in the quickfixj-engine (maybe because its a problem of the data structure from Hotspot or because of a bug) - I hope not, otherwise I have inconsistent data in my system and not only in log4FIX.

Example market data snapshot from Hotspot for log4FIX:
