Unable to close funcSnippetEnabled

[glepnir]

Problem

I set false, it still executes，With some code snippet plugins, they are conflicting. I use coc and neosnippet to help me complete func by neosnippet, but when I type functionname, go-langserver will prompt me, I can't challenge the next snippet. like this pic This is my go-langserver setting in coc

    "languageserver": {
    "golang": {
      "command": "go-langserver",
      "filetypes": ["go"],
      "initializationOptions": {
        "gocodeCompletionEnabled": true,
        "diagnosticsEnabled": true,
        "funcSnippetEnable":  false,
        "lintTool": "golint"
      }
    }
  }
