WooCommerce recently updated their template files. All files which received changes will need to be updated within Understrap. I am already in the middle of this process.
This is to serve as a marker and forum for users which notice the template error's when updating WooCommerce. The updates should take a few days to implement and test.
As an overview, it looks like a lot of changes were based around removing support for older versions of WooCommerce, general cleanup, with a few significant changes here and there. If anyone is finding any bugs using the older versions please let us know.
Thanks ZacharyElkins. The checkout Billing details form has lost its formatting.

Thx, @noelspringer . Gonna close that issue due to the fact that it _SHOULD麓VE_ been solved. Feel free to re-open.
