Repairing two weapons in sequential order only repairs the first

Bug Name:

Repairing two weapons in sequential order only repairs the first​

Bug Description:

Went to repair my Main hand and offhand, just after repairing the main hand with 10 memory fragments, I removed and placed the offhand, but the main hand was still used for repair​

How to reproduce/proof:

Placed Main hand, repaired with 10 memory fragments and 10 Artisan's Memory (bought Artisans after placing the weapon)
After repairing, removed the main hand, and placed the offhand. Bought 10 Artisan's Memory and repaired with 10 Memory fragments
Offhand didn't receive the repair durability, but instead the mainhand did.
"Continuous" Was checked, and offhand had automatically repaired once I bought Artisan's Memory
