The rows’ first cells cannot be translated in the Release timeline section. This helps enforcing consistency for the R abbreviation (even if I would prefer being able to translate it), but forces every language to show weeks. I think the whole cell should be translatable.

Perhaps it should say REL-n weeks were weeks is actually translatable.
I just moved the weeks out of this cell to the introduction at the top. This saves us from having heaps of extra tags. Again a good finding. Thanks!
