URL Parameters not working

Hi,

I have add via widget in sidebar shortcode [adinserter block=”6″]
In settings I have have to show only with get param: utm_source=www.seznam.cz
But block not show any banner. When I remove param settings, then everything works ok. This problem starts after update from version 2.7.14 to 2.7.16 – could you help use what we do wrong? I tried to add to banner only static HTML and another param, but with no success.

Thank for your help!
