Fletchers Giving Trade Results Without Accepting Price

Two fletchers within a village with identical tier 1 trades. When attempting the second trade, 1 emerald to get 12 arrows, I placed multiple emeralds and tried to mass trade with Shift+Right-Click. The trade immediately becomes locked, no emeralds are removed, but I still get 12 arrows. Other trades work fine, and upon making any other trade with the fletcher, the bug becomes resolved. Mass trading with Shift+Right-Click does not produce errors with other trades or Villager types.

What I expected to happen was...:
I expected to place my emeralds in the trade UI and receive 12 arrows per emerald.

What actually happened was...:
Instead, all emeralds remained in the trade UI and the trade became locked. I still received 12 arrows.

Steps to Reproduce:
1. Enter Fletcher trade UI.

2. Cycle to second trade.

3. Place 2+ emeralds in payment slot.

4. Shift+Right-Click purchase slot.

 

Steps to Temp. Fix:

1. Cycle to unlocked trade.
2. Make trade.
3. Exit UI.
4. Re-enter UI.
