laconia | Create well-crafted serverless applications | Serverless library

I'm fairly new to Jenkins but I'm trying to set up a Multi OS Slave environment. Jenkins Master is on Windows Server 2019, and I have a separate Windows Server 2019 slave (Laconia) and an Ubuntu 20.04 slave (Java8Europa) both successfully connected via SSH. I've also configured Git on both instances and I have created two Git tool locations in the global tools config as shown below and confirmed that these work on the individual machines.

The problem I have is that even if I set the individual nodes to use the correct Git tool as shown below, if I try to execute a simple declarative pipeline job, it will only ever use the Git instance which is at the top of the list above (WindowsGit). My declarative pipeline starts with a Windows Script which executes correctly but then when it tries to execute the Linux shell script on the Linux box, it fails as it attempts to use WindowsGit.

I'll include the console log output below, but is there anyway how I can force via the Jenkinsfile which git tool should be used per agent? I did read that there are some tool locations which are ignored by the agents and there are some articles which suggest Git is one of these and the fact that if I switch the order of the Git installations to have the LinuxGit at the top, the pipeline fails to run the Windows script which would seem to support those articles. Any other way I can get around this?
