The green hair strand falls down, affected by gravity (which is correct). The red hair strand is completely immobile - that is the bug.

Such buggy hair strands are often produced when I trim or subdivide hair, but not certain about what exactly causes this. Sometimes it can be cured by rekeying it in particle edit mode.

This is probably the same as T56818: Hair Dynamics does not work for all strands when hair has been cut

Richard Antalik (ISS) mentioned this in T93344: Hair dynamics stopped working after editing and combing in "Particle Edit".Nov 24 2021, 4:51 AM

Thanks for the report. Marking this as known issue since it depends on the old particle settings which is end of life.
