Filters with settings have delete button on settings form, but button does not do anything

I set Filters:
2 x Taxonomy Terms: (first exposed, second not exposed)

Problem is that I cant delete "Taxonomy: Term = Test"

Filters
Node: Published False
Settings
Taxonomy: Term exposed
Settings
Taxonomy: Term = Test
