Wallet finder of the Firefly wallet does not find all Shimmer tokens

[Agmidion]

Hope someone can assist with the following issue.

Some of my Shimmer tokens were locked up in pending transactions.
I therefore removed my profile from the Firefly wallet and recreated the profile again. I used Wallet Finder to find the Wallets with the tokens. My problem: Only 9 out of 20 wallets were found. Hence lost tokens for the remaining wallets.
I fully re-installed Firefly Wallet and I have run the Wallet Finder several times but that did not make any difference:
Wallets searched: -
Wallets found: 9
Total balance: shows part of the balance - locked up tokens are not included

The Shimmer explorer shows the problematic addresses with the correct missing amount of Shimmer tokens as Spendable Balance

Firefly Wallet version 2.0.1
Ledger Nano S with firmware 2.1.0 and Shimmer app version 0.8.1

Your help is much appreciated. Thanks.
