In case of undetected funds in the wallet, please update to the latest wallet release and enter the rescanning commands found in the tutorial on restoring from seed.
Do not do any part of that tutorial that includes actually renaming or deleting files or doing the seed words restore, only do the rescanning commands in the Debug Console, which include:
- rescanblockchain StartingBlockHeight EndingBlockHeight (Starting and Ending blocks are optional)
Further options and address recovery command may be found in that tutorial: https://veil.freshdesk.com/support/solutions/articles/43000472093-how-to-correctly-restore-wallet-from-seed-words-or-find-lost-veil
