"Generate key bindings" conflicting with "Gradle key bindings"
<!-- bug reporting without issue template will be closed automatically -->

## Expected behavior, english is required

If you have a look at the SpaceVim.txt help file on Github master branch, you can see that both [Generate key bindings](https://github.com/SpaceVim/SpaceVim/blob/ae6052b9e082b7a2b13e6661c3164c9bbfe75d46/doc/SpaceVim.txt#L2426) and [Gradle key bindings](https://github.com/SpaceVim/SpaceVim/blob/ae6052b9e082b7a2b13e6661c3164c9bbfe75d46/doc/SpaceVim.txt#L2426) start with the sequence `SPC l g`. If I press that sequence in my SpaceVim, I get Gradle operations. The generate stuff is accecssible via `<Leader> j` but this is not documented anywhere.

## Environment Information

- OS: linux
- vim version: -
- neovim version: 0.4.4
- SpaceVim version: 1.6.0-dev
- SpaceVim status: ae6052b9

```
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean
```

## The reproduce ways from Vim starting (Required!)

Open a Java project or file.
Press `SPC l g` and you get the Gradle keybindings.
Press `<Leader> j` and you get Java autogenerate keybindings.

## Screenshots

Another weird thing. Pressing `<Leader>` and waiting for the guide to show:

The `[j]` has no description.

EDIT: I submitted by error an empty issue at the beginning. Sorry.
