TYPO3 Core

DB Check Module - Full search functionality for advanced queries on e.g. page content
When "making a query" for e.g. CTypes and i'm changing the operator from "is in List" to "equals" i'm getting an exception from the QueryGenerator.php
"InputValue" is an array, causing the strottime() to break. (screenshot as attachement)

Issue Update:
When changing from "is in list" to "equals" not only an exception is thrown but also the values are thrown away.
The right behavior would be to keep the first value and use it as the query property.
