Wallet backup export function doesn't export PSH-P2PK adress+key pairs.

Trying to sweep BTG into Coinomi wallet. Pasted 70 private keys and none of them contain any funds.
I guess all is on those PSH-P2PK addressess i've been using lately.
I've checked used PSH-P2PK address' and searched them in exported file - they are not there.

Would like to sell this BTG while it still worth something.
Is very any immediate solution to this problem??
