Custom Sidebars Pro is taking a very long time to load

Per the P3 Plugin Profiler, the plugin Custom Sidebars Pro is taking 3.6 seconds to load (that’s about 2/3rd of entire combined plugin load time). I have looked at google page speed and other site speed tests and ever since the update to Custom Sidebars Pro version 2.0.9.9 our site is indeed loading slower. Could you guys take a look at that please?

Thank you!
