hexblade martial weapon proficiency missing

HI, I've purchased the hexblade worlock subclass from xanthar's guide to everything. When selected, the character should gain martial weapon proficiency, but it does not. additionally, this subclass should have medium armor proficiency. What have I missed here. Here is a link to the character in question (build in progress)https://www.dndbeyond.com/profile/CounselorOfGods/characters/37091857

a bit more detail in case it's needed; The proficiency comes from the "hex Warrior class feature on P55 of Xanathar's Guide to Everything. Additional, it seems silly to me that purchasing a subclass would not include the spells in the expanded spell list for that subclass

Your character is showing it does have martial weapon proficiency and medium armour proficiency.

I'm not sure I understand your issue.

Hi, so it seems like the proficiency does not show correctly in the character builder, but does show correctly once the sheet is generated. that's a bit less of an issue. confusing, but functional. Thank you for having a look. Really appreciate your help
