Multiple similar filters can lose the existing filter

I think there is a bug in the new Morphia 2.2.3. I translated code from Morphia 1.x and the generated MongoDB queries seem to be mixed up when combining .exits() and .not() and that kind of combinations.

// OLD Morphia 1.x WORKED
q.or(q.criteria("disabled").doesNotExist(), q.criteria("disabled").hasThisOne(Boolean.FALSE));

// NEW Morphia 2.x DOES NOT WORK
q.filter(Filters.or(Filters.exists("disabled").not(), Filters.eq("disabled", Boolean.FALSE)));
);

// OLD Morphia 1.4 WORKED
//			q.or(
//					q.criteria("belongsToContentId").doesNotExist(),
//					q.and(
//							q.criteria("belongsToContentId").exists(),               
//							q.criteria("showAtGuideLevel").hasThisOne(Boolean.TRUE)
//					)
//			);

// NEW Morphia 2.x DOES NOT WORK

	q.filter(
			Filters.or(
					Filters.exists("belongsToContentId").not(),
					Filters.and(
						Filters.exists("belongsToContentId"),           
						Filters.eq("showAtGuideLevel", Boolean.TRUE)
					)
			));

You should use find() instead: https://morphia.dev/morphia/2.2/javadoc/dev/morphia/Datastore.html#createQuery(java.lang.Class)

I tried today if the problem is fixed with morphia 2.2.5, but there still seems to be a problem. STEP 1:

final Query<Event> q = dbs.getDatastore().find(Event.class);
q.filter("customerId", customerId);
		q.filter(
				Filters.or(
						Filters.exists("status").not(),
						Filters.eq("status",0
				)
		);
log.info("Q1: " + q);

Q1: MorphiaQuery[clazz=Event, query=Document{{customerId=5ca0c24a4ac35d7748610e68, $or=[Document{{status=Document{{$exists=false}}}}, Document{{status=0}}]}}]

STEP 2:

			q.filter(
					Filters.or(
							Filters.exists("belongsToContentId").not(),
							Filters.and(
								Filters.exists("belongsToContentId"),              
								Filters.eq("showAtGuideLevel", Boolean.TRUE)
							)
					));
log.info("Q2: " + q);

Q2: MorphiaQuery[clazz=Event, query=Document{{customerId=5ca0c24a4ac35d7748610e68, $or=[Document{{belongsToContentId=Document{{$exists=false}}}}, Document{{$and=[Document{{belongsToContentId=Document{{$exists=true}}}}, Document{{showAtGuideLevel=true}}]}}]}}]

BUG: The filter of status from before is gone?
