One VPN different device gateways

Hi Guys and Girls.

I have a VPN running to our mikrotik at the data center and then our office also connects to the same mikrotik.
At the office we have two mikrotiks using different external IP’s and the network is segmented for internet breakout by having half of the company set their default gateway to 2.10 and the other to 2.1.

When i route my traffic through the 2.10 VPN i can connect to devices that have 2.10 as the default gateway but can’t connect to any other device that use the 2.1 gateway - and then vice versa if I switch the route.

How can I fix this please?
