[BUG] Two error indicators appear in the modeline

[r-darwish]

What did you expect to happen? A single checker indicator should appear for errors and warnings

What actually happened? Two indicators appear

Additional details:

Personal configuration.

I wasn't sure if this is a doom issue or doom-modeline issue. I used doom-modeline outside of Doom Emacs and never encountered the left indicator. The left indicator isn't clickable so I couldn't figure out its source.

Steps to reproduce: Just make a flychecker checker display errors.

It appears to be lsp-rust that is adding a new segment to the mode-line, to global-mode-string, to be precise. There is no setting to prevent this, so we'd have to do it manually. Try this:

(after! lsp-rust
  (delete (list '(t lsp-clients-rust-progress-string)) global-mode-string))

It seems that some recent update caused it to vanish

As of https://github.com/brotzeit/rustic/commit/4f45248f464ee2bcad9c8179b867cbb3eea44ce8 the mode-line modification was moved.
