Composer cant resolve requirements

Running composer I get following message:

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Can only install one of: drupal/layout_plugin[1.x-dev, 8.1.x-dev].
- Can only install one of: drupal/layout_plugin[1.0.0-alpha22, 8.1.x-dev].
- Installation request for drupal/layout_plugin 8.* -> satisfiable by drupal/layout_plugin[8.1.x-dev].
- Installation request for drupal/layout_plugin ^1.0.0-alpha22 -> satisfiable by drupal/layout_plugin[1.x-dev, 1.0.0-alpha22].

Removing

"require": {
"drupal/ds": "^2.0.0",
"drupal/layout_plugin": "^1.0.0-alpha22"
},

from composer.json solves this problem. Layout worked well (choosed 2 column layout from layout modul to see any effect), but I still cant see any contact form link on the profiles page.

I just installed also latest dev of layout plugin.
