All Filter Options not appearing when using custom Filter tag

        <filter id="exceptionFilter"
            <custom name="laneTxId" paramClass="java.lang.String" caption="Lane Transaction ID">
            {E}.laneTxId= ?
            <custom name="postedDate" paramClass="java.time.LocalDate" caption="Posted Date">

In the code shared above, when I am trying to add filters using the custom tag, the search operation works fine, but it only provides the option to filter for values where search value ‘equals’ the property. It doesn’t show the dialog box containing all search options. Please suggest a resolution.
