Microstation will not open Project Wise dialog box to attached references

Microstation will not open the Project Wise dialog box to attach references. Instead it only opens the windows browser.

I'm running Version 10.0.16299 of Project wise explorer. I have loaded the AutoCAD integration module for 2018 (I'm not having the any problems with AutoCAD X-ref's through Project wise). This issue is only with Microstation.
