Incompatibility Free Shipping Bar and Flexible Shipping plugins Woocommerce

Good morning,

My name is Andrea and I am writing from Orden en casa.

We have recently updated the “Free Shipping Bar” plugin but it seems not to be working correctly and it is not being shown on our ecommerce. We have installed and activated after having purchased on Envato website and click “enable” on Woocommerce menú. Also, months ago we have installed a new plugin and have created different cost options named “Flexible Shipping”, could this be the problem? Could it be an issue of incompatibility between both plugins?
To sum up, we’ve got 2 plugins
• Flexible Shipping: to apply the different costs depends on the spent you made. From 50€ onwards it’s free.
• Free Shipping Bar: this is the bar that appears on the main website to let the user know how much is left to reach €50, which qualifies for free shipping.

I think the problema could be the incompabilities between these two plugins…

We have tried to do it our own but cannot find the reason why is not working. Maybe should we deactivate “Flexible Shipping” and see if Free Shipping Bar works?

Please find attached our last invoice and receipt from the plugin update.

Awaiting your comments.

Thanks and kind regars
