2024 Cleric (Tempest Domain) and Divine Order: Do I keep Martial Weapon and Heavy Armor proficiency?

2024 Cleric (Tempest Domain) and Divine Order: Do I keep Martial Weapon and Heavy Armor proficiency?

I have a question regarding the interaction between the 2024 Cleric and the Tempest Domain from 2014.

Under the 2024 Cleric rules, Martial Weapon and Heavy Armor proficiency appear to come from the Protector Divine Order, while Thaumaturge provides different benefits.

However, when I create a 2024 Tempest Cleric in D&D Beyond and choose Thaumaturge, the character sheet still shows proficiency with Martial Weapons and Heavy Armor.

Is this correct under the 2024 rules and the backward compatibility guidelines for older subclasses, or is it simply a D&D Beyond implementation quirk/bug?

More specifically, do older Cleric subclasses that previously granted these proficiencies (such as Tempest Domain) retain them in addition to the Divine Order choice, or are those proficiencies supposed to be replaced entirely by the Divine Order feature?

Has there been any official clarification, Sage Advice, or rules guidance on this interaction?

Thanks!
