Nominal Row Filter Widget drops large Domains

Good day
I am using the Nominal Row Filter Widget in a process where I do data pre-processing on a table of ~50k rows of time sheet data. One of the ~15 columns has project codes. There are about 100+ unique codes, the reason why I have the domain calculated with the Domain Calculator during the data processing. Later in the process I use the Nominal Row Filter Widget on a different column. When I want to filter on the project code column after the widget the column is not available in the Nominal Row Filter node. It seem the domain was dropped by the Widget as I now have to insert again a Domain Calculator node to establish the domain for project codes again.
Is this a bug or by design or am I doing something wrong?
Thx for your feedback.

@kurt have you limited the number of single items the domain calculator does? I think the default is 60. Maybe remove that.

Or use an expression node to create a column that you can then filter.
