Remove custom network

I use metamask with trezor to stake matic on matic network
All was good for a month almost
Today I add custom network polygon to the same meta mask trezor to try to use on different platforms
I didn’t make any transactions yet
After 30 min I log in to matic network staking account and my balance was 0
I’m pretty sure is cos of the polygon custom I add …
Someone know how to remove the custom network with out to remove all my metamask accounts?
Or someone know how to see my balance staking again?
I try to switch to Eth network coz staking on that net but I still don’t see it
Thx guys

Just remove the network and my balance show up
Don’t add custom network will mess your wallet
