Kiwi Syslog Web access - Error (save as filter error)

Hello all,

I'm new to this product so please if someone can help in the following issue i would appreciate it.

I'm getting this error whenever i click on "save as filter" :

"System database general exception.

Parameterized query expects a parameter value which was not supplied.
Parameter name: @CustomSQL"

I didn't integrate KSS with any SQL server (left everything as default)
