As of now, module does not support multilingual very well. Like a node can have different url alias per language, while this is not supported by the module.
1. Enable Content Translation, create node and add translations.
2. Create Views, add url alias field
You will observe duplication of records. Because table has as many records of node based on translations being added.
Impt: Calling views_url_alias_node_rebuild will resolve the issue of duplication, but that's not the solution, as this actually is just a temporary solution, the moment we add translation to the node, records are again duplicated.
Let's store langcode as well in the table.
Support entity translation operations for adding / updating records. As well update existing functions to save corresponding langcode.
Also, we will have to write hook_update to add this field.
I'ld start with creating a patch for this, including following issues as well:

It's likely this issue predates Contrib.social: some issue and comment data are missing.
This issue still valid in term of adding the language filter.
I fixed in 3.x-dev the issue with saving the language dependent data to views_url_alias, but the filter or view query still need to added to make sure we can filter by specific/current language.
