Our team is looking into this. Part of the issue here is that the Donor Dashboard is currently translatable, but not fully compatible with WPML and some other multilingual solutions. The line between our responsibility and the multilingual plugin's responsibility is a bit blurry here.
Issues like this that are not preventing donations or have a simple workaround are generally prioritized at the end of an 8 week development cycle, and then tested and released. That means it can be up to 10 weeks for issues like this to be resolved.
