About the 【Shard Scavenger】 bug

The skill description is triggered every once in a while, but the time on the board is doubled.

For example, the spell is described to trigger every 6.4 seconds, but the panel shows that the trigger interval is 12.8 seconds when the skill is activated. Skill description: Each time you trigger a reload crossbow and a return throw, the panel shows whether the two times are superimposed, or the code itself is wrong.I don't know how to add a picture.
