The "Used Adjectivally" and "Modified by Adjective" headings in the Grammatical Relationships section of the Exegetical Guide are wrong. All the entries listed under "Used Adjectivally" should be listed under "Modified by Adjective" and vice versa.
Here is a screen shot from the latest RC for 4.0a (4.01.3.4467) that illustrates the problem:

Sometimes the results are wrong in other ways, consider this example:


In addition to the previously mentioned problem that this is under the wrong heading (the noun is being modified by pistos as an adjective instead of pistos being modified by an adjective), there is another problem in that adelphos is not modified by pistos in this verse. The noun adelphos is modified by the adjective agapetos while the noun diakonos is modified by the adjective pistos.
I have found the headings reversal to be a consistent problem in every Bible Word Study that I have executed.
