I am trying to create a foreign key in a table using the create table GUI, I can use the foreign key field (which is very intuitive with the drop downs listing the other tables and its fields), however when I click on Ok the table gets created with all fields but without the foreign key constraint.

OS: Linux, Ubuntu 19.10
DB4S: Version 3.11.2 (Installed via PPA)
Workaround: After you set-up FK dont click OK, instead click any other row and then OK.
Thanks @T1mL3arn your point worked perfectly.
