Mysterious Window

[JUNIPER]

       On opening GC 2.2.1 (via Kubuntu) I sometimes get a window entitled
   "Since Last Run" with 3 columns: Transaction, Status and Value. The first
   column shows the names of my scheduled transactions and the other columns
   are empty. I see no purpose for the window, which appears only occasionally.
   I  ignore  it  and close it and everything proceeds as if it had never
   appeared. Been using GC several years now and really like it.
       Just curious.
