Outdated WooCommerce Templates

When going into my dashboard’s back-end, I receive the following error:

Your theme (Kleo Child) contains outdated copies of some WooCommerce template files. These files may need updating to ensure they are compatible with the current version of WooCommerce. You can see which files are affected from the system status page. If in doubt, check with the author of the theme.

When I then click on the status page link, I see the following under Template Overrides (Woocommerce):

kleo-child/woocommerce/content-product.php version 2.4.0 is out of date. The core version is 2.5.0, 

kleo-child/woocommerce/single-product/add-to-cart/variable.php version 2.4.0 is out of date. The core version is 2.5.0, 

Please help me to resolve this issue. Please give me detailed steps for a non-technical web developer if you aren’t going to fix it on my behalf. This WooCommerce page wasn’t particularly helpful because I’m scared that if I do something, I might make a mistake and break my site.

Thanks!
