This behaviour is the same on both V1.4.0 and the latest development release
1.5.0 SVN 34041.

When using VoIP Calls on the attached trace, there are two H.323 calls, which
are correctly shown as being in the completed state. The "FLOW" graph works
fine displaying the H.225, H.245 and RTP for each of the two calls.

However, when using the "Prepare Filter" button, the first call only displays
the H.225. The second call when filtered in this manner shows the H.225, H.245
and RTP.
