Not possible to change Avg pps for multiple streams from "0.0000" to some other value

[biggena]

When all the streams are configured with Packet Rate 0.0, it is not possible to set some other "Avg pps" rate in "Streams" tab. Packet Rate value changes to "nan" and stucks there.

Only way back is to change Packet Rate for each stream separately (inside each stream). After all of them are changed to the same value - "Avg pps" changes from "nan" to this value.
