Castsequence bugging with shaman legendary

When I use my castsequence macro.
‘/castsequence reset=10 chain lightning, chain heal’
And I spam it with my new legendary that makes one instant cast after using the other…
Then it often uses one spell but does not change the macro. And then I get stuck and I have to use cast time to use one instead of having it instant like it should be with the legendary.

This needs to get fixed.
