Explorer doesn't display ERC20 token name, symbol and token holders

[tkeidar]

I've deployed an upgradable ERC20 contract, everything works fine and I interact with it via RPC but the RSK block explorer doesn't display it well - there is no token name or symbol, and the Accounts tab, which should display all token holders, is empty.

The proxy contract implements Open-Zeppelin's OptimizedTransparentUpgradeableProxy
Contract address: 0xd96AA50B7f306ab20425cD6F213128AdF7eb1f0E
Block Explorer: https://explorer.rsk.co/address/0xd96aa50b7f306ab20425cd6f213128adf7eb1f0e
I see that the block explorer recognizes it's an ERC20, but still no token name, symbol or holders are displayed.

The implementation contract:
Contract address: 0x6542a10E68ceAC1fa0641ec0D799a7492795aaC1
Block Explorer: https://explorer.rsk.co/address/0x6542a10e68ceac1fa0641ec0d799a7492795aac1

Both contracts are verified on the block explorer.

Same issue for ZUSD, an upgradeable RBTC-backed stablecoin issued by the Zero protocol:

Proxy: https://explorer.rsk.co/address/0xdb107fa69e33f05180a4c2ce9c2e7cb481645c2d
Implementation: https://explorer.rsk.co/address/0xf3522efc07dcbb273d774a2e6f4d902c44a2e507

Here is a sample ZUSD holder: https://explorer.rsk.co/address/0xd28aaacaa524f50da5c6025ca5a5e1a8cbf84647

ZUSD does not show up in the "Tokens" tab, or the "Token Transfers" tab of the user's address. Even if you go directly to a ZUSD transaction, the transfer is not picked up in the transaction's "Token Transfers" tab: https://explorer.rsk.co/tx/0x68ec06544a7e74efd6d44f0d9780635b19ac6d0361a102626627f1b4e4781449?__ctab=Token%20Transfers

It is very difficult for users to figure out what is going on with ZUSD transactions using RSK Explorer.
