Thank you for waiting. I checked a few things on the website, but couldn't get the plugin to work properly on translated pages. Again, this likely is a compatibility issue between the Buy Once or Subscribe for WooCommerce Subscriptions and WPML.
To verify that, I've created a Sandbox (a testing website), with the needed WPML plugins and WooCommerce setup. You can access it here:

Please install the Buy Once or Subscribe for WooCommerce Subscriptions, setup one product that uses it, and translate the product. The idea is to test in isolation, so only one product is enough to test. Please don't import or create other unnecessary content. Let me know if the behavior is the same there.
I know this takes some effort, so thanks in advance for your cooperation on this matter.
Thank you for sharing. The result was the same, which indicates that this plugin is not WPML compatible, at first. I've escalated this ticket to our 2nd tier team, to see if they can find any workaround.
This might not be possible, and might depend on the WooCommerce's team collaboration. I'll keep you updated.
