Shaper of Storms not adding shock effect from local skill

% Increased Effect of Non-Damaging Ailements on Enemies granted by Unbound Elements seems to not properly work. When the gem is off, I have a Shock Effect Modifier of x 2.1 and shock effect of 52.5% (Max shock is 65% due to mastery). When the gem is turned on, the Shock Effect Modifier correctly goes to x 2.64 but the shock effect stays the same.
If I use the same wording of the gem in the custom configuration everthing works as expected.

With gem off:

With gem on:

With custom config (54% increased effect of non-damaging ailments on enemies)

I know the gem says it affects only supported skills so I made sure that I selected the correct skill in the calculations tab. This error seems to be present in the new 3.26 tree only, as I made the PoB yesterday with the 3.25 tree and there it works as expected.

Riproduci il problema nell’albero 3.26 con Unbound Elements abilitato e la skill interessata selezionata nella scheda calculations. Confronta la formulazione local-skill della gem con la configurazione personalizzata equivalente e con il comportamento funzionante della 3.25. Il lavoro è completato quando l’effetto shock della skill supportata riflette l’aumento dell’effetto degli Ailments non dannosi mentre la gem è abilitata.
