CauseIn values calling any meta whose "group" is NOT ZERO, we get the Meta Count as ZERO. For such meta values we show a value such as  "(10000 - 33%)" for the meta value count. 
This causes the Security Analytics server to throw an Arithmetic Exception while calculating the Percentage values for that Meta.
ResolutionThis issue is permanently resolved in Security Analytics 10.5.1, in which changes have been made in the Security Analytics server to Display "Error - <Number>" as the Session Count when a Non-Positive number is received as the Session Count.
