Selecting Hybrid Warlock class option grants me both the at-will and pact boon from the chosen (hybrid) Eldritch Pact automatically without any options to manually delete them from the powers section. This should not occur for hybrid Warlocks, as stated by the hybrid Eldritch pact class feature.
This one is going to be tricky.... It's happening in the Hybrid Talents... which show up as a drop down, but don't appear to have an editor tab.
Added a Hybrid Talent tab to the Editor.
Still tricky because the buildoptions that contain the pacts are shared by both normal warlocks and the hybrids, but with different rules.
This might be solvable by making new Hybrid pacts that don't bootstrap powers, and making each of the Warlock pacts an option under Hybrid Talent. You could pick the wrong thing then, but it might work functionally the way it should.
This code in the bootstraps on the various pacts fixes the issue
