In your screenshot, it looks like the variations are loading partially off the screen. This kind of problem is usually caused by either a conflict with your theme or with another plugin.
The best way to determine if the issue is being caused by a theme and/or plugin is to temporarily switch your theme to Storefront and disable all plugins except for WooCommerce.
If that resolves the issue, then one-by-one you can switch back your theme and re-enable your plugins, testing in between, until you find the one causing the conflict.
