Hello,
I could not replicate your issue, thus I would like you to review your configuration:
- Network -> VLAN configuration:

Network -> Interfaces section (I assume you do not configure DHCP server, since you have mentioned that you have set IP on your computer manually)

The same applies for the other VLAN with gateway 10.3.0.1.
- Static IP configuration on your computer:

This should be enough to ping and access the gateway:
