✅ Have you read and understood the above guidelines?

yes

🔎 Did you run the script with verbose mode enabled?

Yes, verbose mode was enabled and the output is included below

📜 What is the name of the script you are using?

Docker (LXC)

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/docker.sh)"

⚙️ What settings are you using?

Default Settings
Advanced Settings

🖥️ Which Linux distribution are you using?

Debian 12

📈 Which Proxmox version are you on?

pve-manager/9.0.4/39d8a4de7dfb2c40 (running kernel: 6.8.12-8-pve)

📝 Provide a clear and concise description of the issue.

When running the Docker LXC helper script and selecting 'App Defaults for Docker', it appears to be using the script's defaults, rather than defaults created by the user from previous runs.

The final CT shows that that it was indeed created with incorrect settings such as 2GB RAM instead of 4GB, 4GB disk size over 32GB,

as well as using DHCP instead of the given static IP information

🔄 Steps to reproduce the issue.

Set docker.vars to use user-created defaults over script-created defaults (personal is provided in 'Additional Context')
Run the docker LXC helper script
Select 'App Defaults for Docker'
Note the differences between the defaults file and script output
Verify incorrect settings in the final container

❌ Paste the full error output (if available).

Note: this is the output with verbose enabled in the docker.vars file
