deployctl deploy when using deno.json config offers to add duplicate node_modules exclude patterns

[NReilingh]

I am running deployctl deploy in a deno project with no package.json or node_modules folders. I have allowed deployctl to write configuration to deno.jsonc so that I can run deployctl deploy with no arguments. However when I do this, deployctl complains that the config used differs from config found in deno.jsonc, and offers to overwrite it with --save-config. If I allow this, it adds a duplicate entry to exclude "**/node_modules" on each run:

? Writing to the config file '[...]/deno.jsonc' will remove any existing comment and format it as a plain JSON file. Is that ok? [y/N] n
  i I understand. Here's the config I wanted to write:
  "deploy": {
     ...
  -  "exclude": ["**/node_modules","**/node_modules","**/node_modules"]
  +  "exclude": ["**/node_modules","**/node_modules","**/node_modules","**/node_modules"]
  }
