[Bug] Multiclassing and TRACK HIT DICE PER CLASS

So I'm currently using a non-charactermancer 5e character sheet, and I'm attempting to update my hit die for my newly leveled rogue 7 fighter 1. However, when I set the " TRACK HIT DICE PER CLASS " to on, the hit die section doesn't update as  expected . I see the hit die section expanded to  accommodate  the additional different hit dice, but it's empty and there's no option to add (see images). Is there something I'm missing? Let me know if you need  additional information.

Hi Mana,  Please click the padlock in the hit dice section, and then p lease supply a screenshot of the entire Core page (you cropped it to just hit dice)

Hmmm, the top of the sheet is missing, that contains information that might be useful. Please supply a screenshot containing the top of the sheet. 

Thanks Mana,  I was not able to replicate this.  My suggestion, turn off "Track Hit Dice Per Class", see what shows up as Hit Dice.  If nothing shows up, please change your level (hover over Background, right next to Background is a cog, click it, change level, change it back) and see if the hit dice shows up then. 

That does not fix it. Thanks for your suggestion though. I was able to replicate the same issue on chrome (i usually use opera).

Please PM me an invite to your game so I can come take a look. 

i'm ok, thank you for trying to help. 

I think this happens creating a 5e character the "Characters" ("NEW: BUILD A CHARACTER") feature rather than creating a character in a campaign/game. If this is the case, perhaps a workaround would be to create the character in a game and then export it to the vault or whatever it is called these days?

Hi, I had the same problem once with the hit dice with the "Build a Character" feature. I've not used it again and I do not know what can cause it. Creating the character directly at the thable of the game have not given me this problem with any of the two characters I have. For what is worth, I usually use Firefox for Roll20.
