Plugin fails to add many variations

Hi we sell phone covers and we have huge amount of variations. So we want to create a bump to customers on the basis of the model they select. So we tried making it with your plugin and observed that when we try to add many variations, the plugin creates some issue like on saving the button variations are not added in the list of cart condition. Is it possible to create bump on the basis of attribute condition or can you fix the mentioned issue? Our website url is https://minibay.in. You can try adding 20-30 variations at a single time into a order bump funnel and you will observe that it does not save. Select the variations in bulk.
