There's something funny there...

Replication sets are numbered, not named.

I'd instead expect that you have three sets:

Set 1, with some tables for customers,
Set 4, with some tables for events,
Set 9, with EventData tables.

(Or it could be sets 1, 2, and 3; I don't want to assume either way.)

You could drop set #9 via the slonik command

DROP SET (ID = 9, EVENT NODE = [preferably the origin for set #9]);

(The script also needs to include the "preamble" stuff required in every
Slonik script...)
