Clients can't see other clients

[lechh]

Hello.
I am new to OpenVPN, I just started with a new company and inherited this solution. I've spent the last 2 days searching for how to make VPN clients "see" each other. It seems the remote clients can connect to the VPN, able to access the company LAN, access resources on the LAN. Vice-versa, the computers to the LAN can see the connected remote clients. However, remote clients cannot see other remote clients. VPN is setup in Tab bridge mode. What am I missing?
Below is the server info and config file:
