This is highly similar to the report MC-261418, however I have found another issue pertaining to this.
When falling from a height of two blocks while shifting, which is not high enough to trigger a Sculk Sensor, and then un-shifting, the Sculk Sensor activates.

You can recreate this by:
*
1. Placing a Sculk Sensor and building up two blocks

2. Jump off the two block tower while shifting

3. Un-shifting after you land*
