The tag disappears when the tagged sequencer is loaded as a sub sequencer

The tag disappears when the tagged sequencer is loaded as a sub sequencer.

Reproduction method

  1. Create level sequence A
  2. Add an appropriate sphere to A and attach an appropriate tag
  3. Create level sequence B
  4. Add A as a subtrack to B
  5. Tag of A disappears

However, if you open A directly, not as a subtrack, the Tag remains.

Hello?
How do you create a subsequence with these tags left behind?
Thanks to this bug, I have to set a large number of tags twice or more in a large number of sequences.

postscript, I told about UE4.24.3
