Clickhouse plugin crashes query when using adhoc filters

[Nikolina697]

I use this query:

WITH topx as(select DISTINCT(case when $split :: text = '' then 'other'::text else $split::text end)::text as filter, count() as cnt from $table where $timeFilter and $adhoc group by $split order by cnt desc limit 10)

SELECT
    $timeSeries as t,
    case when $split :: text in (select filter from topx) then $split::text else 'other' end :: text as spl,
    count()
FROM $table data
WHERE
    $timeFilter
    and $adhoc
GROUP BY  spl, t
ORDER BY  spl, t 

It works fine until I apply an adhoc filter, then it becomes malformed and the plugin that uses that filter crashes.
After I applied adhoc filter query looks like this:

WITH topx as(select DISTINCT(case when place : : text = '' then 'other' : : text else place : : text end) : : text as filter, count() as cnt from database_name.table_name where referencetime >= toDateTime(1651034567) AND referencetime <= toDateTime(1651045367) and (number = 20 ) group by place order by cnt desc limit 10)
SELECT
    (intDiv(toUInt32(referencetime), 300) * 300) * 1000 as t,
    case when place : : text in (
    SELECT filter


    FROM topx
),
    then place : : text else 'other' end : : text as spl,
    count()
FROM database_name.table_name data


WHERE
    referencetime >= toDateTime(1651034567) AND referencetime <= toDateTime(1651045367)
    and  (number = 20)
GROUP BY
    spl,
    t
ORDER BY
    spl,
    t

It seems that after the adhoc filter is applied the query becomes malformed, but also if I press Reformat Query without the applied adhoc filter the query is incorrectly formed.

Two issues:

1. all :: are replaced with : : - the space between the colons
2. there is an additional comma after the FROM topx) , then place ... which also breaks the query
