"Copy to rest of modules" resets to default module when selecting none

[MeAmAnUsername]

To reproduce:

1. Select a default module in the settings (I chose productivity 3)
2. go to factory tab
3. Select the empty module for the first module slot in one of the recipes*
4. click on arrow ("Copy to rest of modules")

Expected behaviour: all module slots for that recipe are emptied Actual behaviour: all module slots (including the first one) are reset to the default module.

*first module slot: the slot before the arrow
