Hello, i have my btc in a btc core wallet

I downloaded abc btc wallet and opened it, i saw my btc

Then i closed abc btc wallet and re opened btc core wallet and did send my btc to a trezor wallet.

The inconvenient is that transaction hasn´t been confirmed, and btc core wallet does not update blockchain since i did install abc btc wallet.

I see btc in my trezor, but i check in blockchain.info and says transactions has been made but unconfirmed. What do i have to do to solve this?

thank you for your time
