Change type of foreign key column


I have a table that is referenced by many other tables by foreign keys.
When I change the type of its primary key column of this table, the type of all columns referencing this primary key get changed in all tables as well.


But after I have commited my changes to your teamwork server the columns referencing this primary key are back to its previous datatype. Furthermore the type of those columns can’t be changed manually.

after change of dataype:

after commit:

I am using Version 14.2 Build sp1_20180404
