Blocks Translations not showing up

Some string within the Gutenberg Blocks do not show up translated in cs_CZ even though they are translated in the PO/MO files. This applies both to some translations provided by the default translation that comes with WC and custom translations.

I tried translating both using Loco Translaslate and POEdit.

For example on the Checkout page there’s an email field. The EN label is Email address and is translated in the default translation files, however is still shows up in EN instead of cs_CZ.

On the Checkout page the same issue applies for:

• Email address (field label)
• Phone (field label)
• Order summary (block heading)
• Total (order total line)
• Including XY… (tax details under the order total)

Expected behavior

Texts show up translated based on what’s in the MO files.

Actual behavior

Texts do not show up translated according to what’s in the MO files.

Steps to reproduce

1. Add a product to cart
2. Go to checkout page
