This plugin is interfering with another plugin

Hi,
I have a bundled product plugin which is failing to work, as when bundled products are added to the chart, costumers are getting charged doubled.
After some plugin troubleshooting, I found out that it’s this plugin who causes the problem. I’ve tried to solve the problem by changing the settings myself, but without luck. Is it possible for you to figure out how to solve this problem?
