Bounty Goal in BTC mode does not display the correct amount

Set goal of 2btc
“David Rappo set a bounty goal of ฿0.005”
This should be “set a goal of 2 BTC”

If I reload the page, it now says the goal is set:
"My Goal:" is now 1.991017270917257
this should be rounded to 3 digits

If I switch to USD, the displayed amounts are correctly updated, but the number in “My Goal” remains 1.99…
The amount in the form should be updated as well
