Lost BTC transferred to trade wallet

I was trying to sell some of my BTC and transferred the funds needed to the wallet address bisq gave me. The funds briefly appeared for a moment under trade wallet balance and then I received a prompt stating that I needed to update my client and now it states that there are no funds in my trade wallet balance.

What should I do? I definitely transferred the funds to the correct address.

since the funds were sent and you saw them appearing in your wallet, it is possible that for whatever reason the SPV wallet lost knowledge of the transaction; do an SPV resync by going in settings > network info > delete spv file and resync
