Wrong results with cross model join on 2 varchar fields

I'm using Teiid 8.11.3 with H2 translator.
I'm joining 2 h2 tables from 2 different teiid models linked on varchar fields.
the query result is retuning empty values from the joined table even though the joined values are identical.

You find attached a zip file containing 2 h2 DBs for a simplified example

Here is the query used:
_select "Customer"."City" as "Customer_City","Customer"."CustomerID" as "Customer_CustomerID","City"."City" as "City_City","City"."CityID" as "City_CityID"
from "db2"."Customer" "Customer"
LEFT JOIN "db1"."City" "City" ON "Customer"."City" = "City"."City"_

Note that if the 2 tables are in the same model, the query return correct results.
