Seems this bug from my earlier post is still not fixed…
If in the feature selection filter node, all the number of features are the same, OR you try to select an alternative solution which has the same number of features as the one already chosen, then it does not carry out the requested action, it still keeps the original selection.
This is despite '‘Select features manually’ being selected.
Thanks for bringing that bug up again (internal reference: Ticket AP-15928). I talked to the development team and they will investigate it in the upcoming scrum. Hopefully, it will be fixed for the next release.
