Cannot write to tags in a remote tag provider

I am using an ignition edge and a standard ignition gateway connected over a gateway network. there is a PLC connected to the edge and I have set up a remote tag provider on the ignition gateway and can see the remote tags. however i cannot write to them.

I checked both the Security Zones and Service Security in the main Ignition Gateway and as far as i can tell it is set up correctly (as shown below). Is there something i am missing? if so please let me know, thank you.
Security Zone Setup

Service Security Setup (The blacked out name is the remote tag provider- it was inherited but i changed it to readwriteedit to see if that would fix it, it didn't)

The Edge node also has to be configured to allow writes and/or edits from the standard gateway.
