The docs say there should be bip39 seed under cashu tools but it isn't there.

You are likely stuck on the legacy seed format. You can try the Delete all Cashu data button under the Cashu Tools menu.
Then you can likely restore you old funds using the new Legacy seed recovery tool in the same section.
so if cashu data is deleted, a "legacy seed recovery" tool will appear in the "cashu tools" menu. There isn't that option currently. Thank you for the help.
