Strangely enough, when hovering over the numeric value, a tooltip with "Filter x10" appears next to the inserter icon.
Find here the blueprintg string to reproduce the issue.
Reproduction steps:
- Plop it down
- Open the parametrization configuration screen
- Confirm the changes.
- Open the parametrization screen again
- Check that the value for the inserter stack size has been saved as "1", instead of the value you saved
