Some swimming activities are not fetched by combined predicate

I'm using following filters to fetch swimming activities from HealthKit.

For some users it fetches all workouts (pool && open water) but for other it skips some open water activities. See screenshot, all those swimming activities are not fetched by following code.

let startDate = Calendar.current.date(byAdding: .month, value: -1, to: Date())!
let endDate = Date()
        
let swimmingPredicate = HKQuery.predicateForWorkouts(with: .swimming)
let timePredicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: .strictStartDate)
let predicate = NSCompoundPredicate(andPredicateWithSubpredicates: [swimmingPredicate, timePredicate])

let query = HKSampleQuery(sampleType: .workoutType(),
                                  predicate: predicate,
                                  limit: HKObjectQueryNoLimit,
                                  sortDescriptors: [.init(keyPath: \HKSample.startDate, ascending: false)],
                                  resultsHandler: { [weak self] query, samples, error in
                                  ...

Could someone help with ideads what is missing in this case?
