Historic not listing tickets with same sigla

[juanzapatac]

I configured several services using same sigla (A for different services).
After I called 3 tickets I noticed that Painel Web did not show any historic ticket until I changed A for B and C, etc.

The reports shown correctly historic informations.

Probably the compare code to move a ticket to historic only is based in A + consecutive number (In my test we have 3 A1 tickets) and it shoud be compare with ticket number + service id, and service name shoul be presented beside or below the ticket number inside the historic column.
