wrangler ignores KV bindings in config

I've used the following in my wrangler.toml: 
kv_namespaces = [
  { binding = "BROWSER_SCREENSHOT_CACHE", id = "xxx" }
]
kv_namespaces = [
  { binding = "BROWSER_SCREENSHOT_CACHE", id = "xxx" }
]
. However, once I deploy the worker, the KV binding gets removed and is no longer available in the code and not visible in the dashboard as binded. However, I can add it in the dashboard and it works thinkies the wrangler.toml code by the dash doesn't change anything, it's the same)

Any chance you have different configuration parameters for different environments?

What's your full wrangler.toml?

name = "browser-screenshot"
main = "src/worker.js"
compatibility_date = "2023-07-25"
compatibility_flags = [ "nodejs_compat" ]

[placement]
mode = "smart"

browser = { binding = "MYBROWSER", type = "browser" }
kv_namespaces = [
  { binding = "BROWSER_SCREENSHOT_CACHE", id = "xxx" }
]
name = "browser-screenshot"
main = "src/worker.js"
compatibility_date = "2023-07-25"
compatibility_flags = [ "nodejs_compat" ]

[placement]
mode = "smart"

browser = { binding = "MYBROWSER", type = "browser" }
kv_namespaces = [
  { binding = "BROWSER_SCREENSHOT_CACHE", id = "xxx" }
]
(is the kv id something i have to censor?)

Nope, but you need to move stuff above [placement] or change it to be tables as well. 
name = "browser-screenshot"
main = "src/worker.js"
compatibility_date = "2023-07-25"
compatibility_flags = [ "nodejs_compat" ]

[placement]
mode = "smart"

[browser]
binding = "MYBROWSER"

[[kv_namespaces]]
binding = "BROWSER_SCREENSHOT_CACHE"
id = "xxx"
name = "browser-screenshot"
main = "src/worker.js"
compatibility_date = "2023-07-25"
compatibility_flags = [ "nodejs_compat" ]

[placement]
mode = "smart"

[browser]
binding = "MYBROWSER"

[[kv_namespaces]]
binding = "BROWSER_SCREENSHOT_CACHE"
id = "xxx"
Basically, since you defined a table ([placement]) then anything under that until another table or EOF, is under the [placement] table. You basically defined placement.browser & placement.kv_namespaces, rather than having top-level browser and kv_namespaces keys. Using tables ([browser] and [[kv_namespaces]]) avoids that. If you don't want to use tables for those, just move the browser and kv_namespaces lines above [placement]
