mobile drop down menu problem

Hi, I am using Embark child theme by Themovation. I noticed there is a plugin conflict w/ my theme possibly and have notified the theme developers. When your plugin is turned on, the mobile dropdown menus stop working and stop dropping down. Also I cannot click on the parent link of the dropdown menus if they direct to a URL. The menus still work on desktop but not mobile. As soon as I turn the download manager plugin off, the menus start working again.
The theme’s support team is really great and they are aware and looking into it. Just letting you know. thank you.

hi i just disabled the bootstrap js as suggested by my theme developers and it seems to be working. thx!
