v0.28 / Categories not visible for proposals

[aramollis]

Describe the bug
I'm not sure if is related to Awesome, but I reproduce this error in https://decidim-awesome.dev.pokecode.net and note in try.decidim.org
When you create a proposal if you define a category eg "Ivan" isn't visible in the preview neither when the proposal is published

To Reproduce
Steps to reproduce the behavior:

1. Go to proposal component
2. Create new proposal & define a category eg. "Ivan"
3. In the preview you the category seems empty. When you publish the proposal the category isn't visible

Expected behavior
The category should be shown
