PDFNET Android 6.7.0 PDFViewCtrl.findText() does not highlight text.

I’ve read before that PDFViewCtrl.findText() should find text and highlight the text. I have it finding text but there are no visible highlights. Is there something I need to do before calling PDFViewCtrl.findText() to make it also highlight text?

This is the exact function I am calling.

mPDFViewCtrl.findText(binding.getSearchText(),false,true,false,false);

That should work. What platform/OS are you on, and what version of PDFNet?
