Sequencer Animations not Blending with Anim BP

Hi, I have a problem when it comes to using sequencer with a character that has an Anim BP and playing animations on that character.

The animations are working fine, until the movement mode in the character is set to “use animation blueprint”.
When its set to custom, the animations blend correctly. This is pretty big problem because I was counting with that it would work. Not it seems that I have to do everything in state machine.

I have also tried keyframing the “set movement mode” value, so during the sequence its set to custom, and at the end it sets to “use anim bp”. Unfortunately that does not work either.
Can anyone help with this?
Thank you.

Ok, so apparently this has been fixed in 4.20. Now the blending of individual animations work with blueprints seamlessly.
