Duplicating daylight sensors

Hi there,

I found a fairly substantial bug while on my realm in which I can duplicate daylight sensors. Details:

1. Xbox One (didn't test on other devices)
2. Survival realm/ cheats never activated
3. Able to replicate the issue 100% of the time

With a silk touch (no other enchantment) diamond pick purchased from a villager, if you place a daylight sensor and break it with the pick, you will get 2 sensors back. I haven't tested this with any other items/ blocks, or with any other silk touch items. I don't believe that this is expected functionality. I've got all the daylight sensors I need now, so feel free to fix at your convenience.

Not sure which version I'm on, but I'm up to date.
