Search box auto completion filter dos not work

[Ariane]

Hello.
I'm running on Metabase v0.55.6

I have a table with a category column with more than 1,000 distinct values.
The dropdown list filter can't work as it's limited to 1,000 values, so I tried to implement search box filter on this colum, as I saw this advice on the forum.

For some cards/dashboards, it works and when I begin to type a word, I have a list of choices matching my words. But for other cards, for the same filter on the same column, autocompletion does not work so I have to type the entire correct value which is complicated (see screenshot).

I tried to adapt the metadata but nothing it's working. I have no solution here, can you help me understand why ?

What's the difference between the cards this works and the cards that don't work? Since you're saying the filter is linked to the same column

There is no difference, it's a SQL queries with several CTEs, and the filter is applied on the same level

both of them are field filters? Can you share some screenshots ... If it works for 1 but not for the other something different has to be

Yes I'll try to send you as many as possible. Thanks =)
Screenshots 1 & 2 are an example where autocompletion is not working. The filter tested is {{od_name}}, field filter if carpool_requests.od_name.

Screenshots 3 & 4 are an example where autocompletion is working. The filter tested is the same : {{od_name}}, field filter if carpool_requests.od_name.
