The weight for some of the equipment items is wrong (they appear to be missing decimal points).

A torch should be 1 lb., not 10 lbs.
A day's rations should be 2 lbs, not 20 lbs.

There may be other errors, but this is what I have noticed so far.

Never mind... didn't see the quantity piece.

I have a weird one. One of my players has nothing in their equipment, but it shows 128lbs of equipment weight.  Any thoughts on what's causing this bug or how to fix it? 

Is it showing 128 lbs of equipment weight, or that they can vary 128 lbs of equipment?

123.8 lbs of weight, my bad, it is very specifically 123.8 lbs of weight.
We have removed everything from their inventory, and that is the minimum carried weight it will show for them.
Their entire equipment list weighed roughly 67lbs (85 with backpack and bag of holding), prior, so we have no idea where this weight is coming from.

Please post a link to the character sheet so someone can look into it for you. Post the actual URL, not the “share” link, and make sure the chat is set to “public,” not “private” or “campaign.”

We have since put items back into his inventory, but I will link it

Here you are, it's just been a head scratcher.

The extra weight is coming from the coins (Coins:123.80000000000001lb.) 
Left clicking on WEIGHT CARRIED, opens and populates the sidebar with the weight break down. The Ignore Coin Weight option in the Character Builder settings must be disabled. By enabling it, the character page will not include coin weight.

Oh! LoL, I had told them to disable it and I hadn't even noticed that they had enabled it.

I'm dumb, thank you so much!
