Using Logos 9.5 Beta 3 on macOS Big Sur 11.3, replicated Syntax Search highlighting of non-selected words being unreadable yellow text on white background:

Inverted image shows lack of contrast in Syntax Search unselected words:

Work around is adding SBL Greek NT for corresponding search results (from Cascadia: SBL Edition)
Not like Video 10 in the Logos 9 Advanced Bible Study Series showing Syntax Search creation without looking at Clause Visualization. Does not show illustrate disconnect between pop-up in Graph Visualization and what needs to be selected for Syntax Search: e.g. screen shot shows "verb" pop-up while not indicating "Terminal Node" is the corresponding Syntax Search selection. Choosing Word instead of Terminal Node in Syntax Search causes zero results.
