2 log analyzer with same setting- one with error

Ground Control Software Mission Planner
1

I am attaching screen shots of 2 log analyzer with same settings, except the following differences. Got error msg (also attached) when downloading log analyzer for Bixler2 running AP4.0.5.

  1. Log_Bitmask : Bixler2 – 65535 Quad – 655358
  2. FW : Bixler2 – AP4.0.5 Quad – AC4.0.3

Review a log works in both cases.
