Shimmer and Assembly token count is negligible after upgrade

[sankarpothukuchi]

I got Shimmer (Total: 180,359,334) and Assembly (Total: 722.118) airdropped in my wallet for staking IOTA tokens in late 2021-early 2022. I just left the tokens untouched. The Firefly version was 1.3.0.

Yesterday, I upgraded my Firefly to version 1.6.5 and now it is showing only 58.08 Shimmer tokens and 232.39 Assembly tokens.
(The Shimmer tokens must be more than 180 million).

Not sure why. Please help !!
