Interrogative Types for Second Person

[Barachia]

Describe the bug
When creating an interrogative type question, the verb does not pick the correct form.

To Reproduce
Steps to reproduce the behavior:

Lexicon lexicon = new XMLLexicon();
NLGFactory nlg = new NLGFactory(lexicon);
Realiser realiser = new Realiser();
SPhraseSpec clause = nlg.createClause("you", "think");
PPPhraseSpec aboutJohn = nlg.createPrepositionPhrase("about", "John");
clause.addPostModifier(aboutJohn);
clause.setFeature(Feature.INTERROGATIVE_TYPE,InterrogativeType.WHAT_OBJECT);
String realisation = realiser.realiseSentence(clause);

The result is:

What does you think about John?

Expected behavior
The result should be:

What do you think about John?

Screenshots
If applicable, add screenshots to help explain your problem.

Java version
Tested with JDK 8 and 13.

Additional context
It seems that in the original SimpleNLG there is a test in which it selects the appropriate verb. See the method testWhatObjectInterrogative() at line 814. The same goes for a Dutch sentence, configured like this:

Lexicon lexicon = new simplenlg.lexicon.dutch.XMLLexicon();
NLGFactory nlg = new NLGFactory(lexicon);
Realiser realiser = new Realiser();

SPhraseSpec phrase = nlg.createClause();
NPPhraseSpec subject = nlg.createNounPhrase("Jij");
subject.setFeature(Feature.PRONOMINAL, true);
subject.setFeature(Feature.PERSON, Person.SECOND);
phrase.setSubject(subject);
phrase.setVerb("doen");
phrase.setObject("dat");
phrase.setFeature(Feature.INTERROGATIVE_TYPE, InterrogativeType.WHY);
phrase.setFeature(Feature.TENSE, Tense.PRESENT);
String result = realiser.realiseSentence(phrase);

The result: Waarom doet jij dat?, the expected result is Waarom doe jij dat?

For the What do you think about John? sentence, the contents of the realization:

SimpleNLG NL:
{realisation=null, category=SENTENCE, features={interrogative=true, textComponents=[InflectedWordElement[what:NOUN], [InflectedWordElement[do:VERB]], [InflectedWordElement[you:PRONOUN]], [InflectedWordElement[think:VERB], [[InflectedWordElement[about:PREPOSITION], [InflectedWordElement[John:ANY]]]]]]}}

Original
{realisation=null, category=SENTENCE, features={interrogative=true, textComponents=[InflectedWordElement[what:PRONOUN], InflectedWordElement[do:VERB], InflectedWordElement[you:PRONOUN], [InflectedWordElement[think:VERB], [[InflectedWordElement[about:PREPOSITION], InflectedWordElement[John:ANY]]]]]}}

It could have to do with that What is a pronoun in the one case, and a noun in the other case?

[Barachia]

It seems to have to do with the morphology of the verb buildPresentVerbPhrase()when there is an interrogative type, then also the Dutch version works.
