unexpected DRCs after changing mechanical pads of USB-C connector

Manfred1

I am refering to the USB-C connector JAE DX07S016JA1. It's symbol contains a non-plated hole and slot. presumably for improving mechanical ruggedness.

The symbol is drawn with imperial units, but our pcb manufacturer uses metric drills, which are avaiable in 50µm steps of diameter.

So I made a backup copy of the symbol (the .dra-file) from within the file-explorer. Then I opened it, identified the pad-files of the hole and the slot. I opened both pad-files, adjusted and changed them to metric units and saved them with a different name, refering to the metric units.

In the symbol, I replaced the hole and slot (pins) with the newly created pads and saved the .dra-file with the same name as before.

In the layout I chose "Placement edit" as application mode, selected the USB-C connector's symbol and in the context menu chose "Quick utilities" / "Refresh symbol".
But now a lot of new DRC errors emerged, even several Pad Soldermask to Pad Soldermask Spacing errors between pads that I did not even touch!

I tried to find out about possible reasons for new DRC errors in the documentation "Help" / "Documentation" burger menu "Allegro PCB Editor" / "Allegro User Guide" / "Creating Design Rules", but did not suceed.

Can you guide me into the right direction?

    Note from a moderator (I don't cover this specific forum but approved this post): The reason this got flagged as potential spam (it's clearly not spam) is because it contains external URLs. Historically we have had a lot of spam on the forums which just clone a post and add a link to some external dubious site - and rather than annoying everyone in the user community with lots of spam posts (which happened in the past), there end up being a relatively small number of posts that do have to go through an approval process to ensure that we keep our users free of bad posts which are very hard to detect otherwise. My apology for the inconvenience. I'll see if we can get the wording changed on how it is reported back to you.
