Oh no, 10 minutes ago the total balance was available and now the old situation has returned! this is how it looks (again):
avail: 0.0002
pend: 2.8
total: 2.8002
I'm flabbergasted, this can't be

Can you try this:
Click Settings > Options > Wallet > Enable coin control features > OK
Click Send > Inputs > check the "Received with address" for your 0.0002
BTC.
Is that address 16u1VqPgTnGrAXQreLFBbVoUkgaATeHXKA ? (It should be)
Anyways 2.8 pending is better then 0 total

But it
can't be after a zap & rescan, it should be confirmed. Something is definitely off.
thanks guys (will make my payment from electrum then LoyceV

)

Electrum, set up a new wallet, safely write down and store your word seed phrase, and sweep your private key from Bitcoin Core. Don't bother importing, just sweep it onto a new address in Electrum and go from there.
To get your private key out of Bitcoin Core:
Click Help > Debug Window > Console > Enter walletpassphrase yoursupersecretpassword 300
(the above unlocks your wallet for 300 seconds)
Enter dumpprivkey 16u1VqPgTnGrAXQreLFBbVoUkgaATeHXKA
This should show the private key. Sweep it into your brand new Electrum (and pay a high enough fee).
Assuming you have the private key to 16u1VqPgTnGrAXQreLFBbVoUkgaATeHXKA, this should work. If you don't have the private key, you're screwed
DO NOT post the private key!Update: you keep saying 2.8, and I assume that's the 2.9 from
633f05443310c5012c5a0360299c3627b8d838af1fbe4aa4a4ab20d74521d04b. I'm starting to think the 2.8 is from a different transaction, that would mean the 0.0002 is from a different address, and that would mean 16u1VqPgTnGrAXQreLFBbVoUkgaATeHXKA isn't part of your wallet.
