[bug] Wrong hreflang

Hey there when a custom slug is made the site generates hreflangs based on custom slug insted of getting it from list of slug, can this be hot fixed?

For example, plugin generates:

<link hreflang=”en” href=”http://localhost:62781/en/deutsch” rel=”alternate” />
<link hreflang=”de” href=”http://localhost:62781/de/deutsch” rel=”alternate” />

But there should:

<link hreflang=”en” href=”http://localhost:62781/en/english” rel=”alternate” />
<link hreflang=”de” href=”http://localhost:62781/de/deutsch” rel=”alternate” />
