Cannot translate strings

Hello,

I am using Ocean WP theme and Ocean eComm Treasure Box?plugin.

I ran into a problem while translating some strings. The strings are already translated using the Loco Translate plugin, but the originals are displayed directly.

The lines:

Apply Coupon (in Checkout Page)

Coupon code (in Checkout Page)

Order Details (in Thank You Page)

Address (in Thank You Page)

Could you help me to fix this?

Best regards,

Au?ra
