Bitcoin balance in swap tab displays 0.000000 even though in wallet tab it shows correct balance

[pokefan77]

There is definitely bitcoin in the wallet. its some kind of bug showing 0 balance in the swap tab

ways to reproduce:
?

[Einliterflasche]

This must have something to do with the way we calculcate the available bitcoin balance. There is some calculation made which deducts the expected network fees.

[pokefan77]

"Syncing Bitcoin wallet" or similar also does seem a bit troublesome in general when trying to take offers for example
if that helps.

[Valerie-5]

How do I fix this issue?
