Research direction

Start at the FilterExpressionBuilder entry point and reproduce the example with a List containing two values. Trace how the list is represented as a filter parameter, then verify that the resulting parameter type or description is no longer misleading and add coverage if the project’s existing tests provide a suitable location.
