Storyline 360 Multi language timelines changing on publish

Hi,

 

Running the latest (May 12/2026) version of Storyline, but this was happening prior to that as well. I have an English file I've translated to Spanish. So 2 languages.

After I publish I have this:

Anyone else have this issue and how did you fix it if you do?

Thanks,
