Exegetical guide inconsistencies

I've run the Exegetical guide in three ways for virtually the same passage and gotten three different results.

For John 1:1-4 (not one of the suggested pericopes) I get nothing under Grammars.

For John 1:1-5 (a suggested pericope) I get two different results depending on the pericope I select.

For the pericope called "In the beginning was the Word" I get some grammar information and visualizations

If I choose the pericope called "The Deity of Jesus Christ" I get no grammars but I do get visualizations
