Woocommerce gift cards plugin causing conflict

Hi all – left this is a general woocommerce forum as well but may be better to post here.

We have had this plugin working fine for over a year now. all of a sudden, when we go to place a manual order on the backend “woocommerce > orders > add new” – it wasn’t let us choose a customer from the drop down menu, wouldn’t let us create one, and wouldn’t allow us to add products. (I dont know about the front end)

But after turning off numerous plugins it appears that this plugin is causing the issue. with it turned off it appears our ordering is fine. Is there a way to fix this issue in the plugin itself or does woocommerce have to have an update to fix it?

Thanks
