Delve Helmet Mod Bug

The following four delve mods appear to have inconsistencies in between the data-mined information, in-game behavior, and trade website display.

Datamined Mods:

"

Nearby Enemies have -9% to Fire Resistance
-9% to Fire Resistance

"

Nearby Enemies have -9% to Cold Resistance
-9% to Cold Resistance

"

Nearby Enemies have -9% to Lightning Resistance
-9% to Lightning Resistance

"

Nearby Enemies have -9% to Chaos Resistance
-9% to Chaos Resistance

In-game behavior
All four delve mods show the nearby enemies portion and not the second portion. None of them impact player resistance negatively.

The advanced mod description does not show any effect from the second part of the mods.

Trade Website:
The extended mods from the fetch have negative resistance, but it is not hashed in the fetch.

The negative resistance is not displayed unless the item has another source of that same resistance. In this situation it displays the affix as affecting the stat, but does not actually impact the numerical value:

The following search displays this behavior:
