UE5.7 Preview – Sequencer Forces Custom Mode, Overrides Animation Blueprint

I can’t get my Animation Blueprint to work in Sequencer in 5.7 Preview. When the animation begins—whether blending is enabled or not—it always switches the animation mode from Animation Blueprint to Custom Mode. This overrides the ABP with the animation from the Sequencer track, completely ignoring the slot name and I can’t change it when play cursor on animation.

The “Force Custom Mode” checkbox is, of course, disabled.

Is there any way to completely disable Custom Mode for now?

I fixed it by disabling Sequencer Anim Mixer addon!
