[Probability Shown 5% Even With One Campaign And One Banner]

I'm experiencing the same issue when there's at least two campaigns in a zone, one contract and one remnant campaign. The remnant campaign takes up 95 % probability while the contract campaign stays at 5 %.

 

From my understanding I thought remnants are there to hop in as a fallback when all other contract campaigns in that zone have reached their limits or simply have expired.

 

Is the behaviour I'm experiencing expected?

To chime in: I do have the exact issue. One zone, one assigned contract campaign with only one banner. And that banner has a probability of just 5%.
