XML additional transforms

I seem to be having issues doing additional transforms that have worked in the past.
I have tried both the additional transforms of

bin\Web.#{OctopusEnvironmentName}.config => Web.config
Web.#{OctopusEnvironmentName}.config => Web.config

Neither appear to even be considered when i look at the raw output, whereas other deployments i have will show the config being transformed.

I have only noticed this happening since I updated to 3.0.1 and now the simple connection string transform that I could do before no longer works. I have attached some screenshots of my deployment process. Any help would be much appreciated
Cheers

Hi,

Thanks for reaching out. We fixed this behavior in version 3.1.3 https://github.com/OctopusDeploy/Issues/issues/2032 . Please try to update to that version and let me know if it works after that.

Thanks,
