a)what does: "quantity of bitcoins" balance show
b)what does: "value of the bitcoins based on the current price" balance show

i would think ethically if you deposited say 1btc... a)=1btc,  b)=0

if you however traded half that bitcoin in the past to be holding some as dollars
a)=0.5btc, b)=
and a second table elsewhere for the dollar side
a)=$300,  b)=
where the balance (shown in one colour) is the varied estimate (of said same colour)

an after thought
double check the balance/valuation of all the currencies as you may find you have balance elsewhere. which is causing the "valuation" hiccup.
if not.. then something very unethical and scammy is going on
