WooCommerce Variant Issue with German Language Selection

Hello,

I’m facing an issue with WooCommerce product variants on my site when switching the language to German. Here are the details:

1. Variants with sizes work fine in Polish.
2. Switching to German, the variants remain, but their sizes disappear and can’t be reassigned.
3. Switching back to Polish, everything functions correctly again.

I’m not using any translation plugins, only the built-in WordPress language functions. The issue only occurs with the German language setting.

Has anyone experienced something similar or can offer a solution?

Thank you.
