- Transport belt
- Rail
- Copper cable
- Underground belt
There are more of such recipes but these are sample ones to reproduce the issue.
What it means they craft x2 items is indicated by this number on mouse hover:

Therefore when left click on it to craft it, it will craft the indicated amount (2), however the bug is that this number won't be indicated in lower left corner where items are crafted, it will always show that 1 item is crafted instead of 2 (or some other value as indicated in tooltip in previous screenshot):

Expected behavior:
Lower left corner (2nd screenshot) shows actual amount being crafted as indicated on item mouse hover (2 in example of a transport belt, rail etc.)
Reproducible save file and log file are attached.
