Latest commit doesn't start the nodes

[stormeye2000]

Running on a EC2 Ubuntu instance and in a Docker Debian image
Running against node release-1.5.6

The current main branch builds and compiles ok
But the nodes are all showing exited when viewing the status
Also errors in the error log:

The error shown is:

Error: decoding from TOML error: data did not match any variant of untagged enum ActivationPoint for key protocol.activation_point at line 316 column 1

Caused by:
data did not match any variant of untagged enum ActivationPoint for key protocol.activation_point at line 316 column 1
Error: "/home/ubuntu/cctl-local-build/cctl/assets/nodes/node-1/bin/1_0_0/casper-node" "validator" "/home/ubuntu/cctl-local-build/cctl/assets/nodes/node-1/config/1_0_0/config.toml" exited with error

When I reset the CCTL git branch locally and rebuild it works as expected:
git reset --hard ac3a941b3d6170027fd175d39fb708ce9c794369

SHA ac3a941 is from Feb 22 and is the commit I built CCTL Docker images for the Terminus tests
