**Summary**:
I'm a regular ContentTranslation user, and I'm somewhat satisfied with it. However, I found an issue when selecting the content translation provider (eg. Google Translate) as the default. It sucessfully translate the paragraph with the selected content translation provider, but when I click on **Keep as default** (**Guardar como predeterminada** in spanish), the section dissapears from the sidebar and default content translation provider is not saved. Developer tools' Console on browser shows anything, so, I cant identify any issue in browser-side.

**List of steps to reproduce** (step by step, including full links if applicable):
* Click on right pane for translating paragraph
* Choose Google Translate as content translation provider
* Text ins translated using Google Translate
* Click on **Keep as default**
**What happens?**:
Box containing the content translation provider chooser dissapears, and default content translation provider is not saved
**What should have happened instead?**:
Google Translate is kept as default content translator for further paragraph translations
**Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc**:
* Happens in the latest production MediaWiki version (any Wikipedia)
* Happens in any browser I tested: Brave, Chromium-based Microsoft Edge and Firefox
Also, content translation provider should be saved as user preference and not browser-locally.
And also, I suggest to use Google Translate instead of Apertium as default content translation (as it is utterly inaccurate).
