The ink pen cost doesn't show in the Manage Equipment view. Same for torch. I think it may be any item whose cost is in copper pieces.

I think I remember the source of this bug being a misplaced decimal point on copper costed items. There is a ticket (pretty sure), but character sheet bugs take forever to get fixed (that dev team is always involved in multiple projects).

Thank you for the report! I have raised a ticket for this issue.

Never hurts to have multiple bug reports, but I was previously told this about this bug:

Hiya,

there's a known issue where equipment costs in Copper Pieces are handled incorrectly.

It's a decimal place issue with the way those costs were entered and is on the active issue resolution stack for one of the dev teams.

This issue should now be resolved!

Can confirm!
