Productivity Modul 2 -> Quality module 2

[Unelin]

Hello everyone
I found a bug that causes all Productivity Module 2s in the inventory to turn into Quality Module 2s.
It doesn't matter whether I move myself or am moved by a conveyor belt, as soon as I get close to the Electric furnace, they turn into Productivity Module 2 in my inventory and in the inventory of the drones.
I used Bluprint and drones to convert the Electric furnace from Quality Module 2 to Productivity Module 2.
Some modules in the Electric furnace couldn't be replaced immediately due to a lack of items. Then I noticed it.
When I dismantled the Electric furnace, everything was OK again.
