Recurring event issues on android devices

I encountered some issues on different android devices and using different calendars when creating recurring events in an ionic app.

Steps:

import { Calendar } from '@ionic-native/calendar';
...
constructor(private calendar: Calendar, ...) {
}

...
// create a recurring event
await this.calendar.createEventWithOptions(
    "Title example", 
    undefined, 
    "Note example", 
    new Date(2020,6,1,18,30,0,0,0),
    new Date(2020,6,1,18,45,0,0,0),
    {
        calendarId: "1",
        firstReminderMinutes: null,
        recurrence: "daily",
        recurrenceInterval: 1
    }
)

// create a second recurring event
await this.calendar.createEventWithOptions(
    "Title example 2", 
    undefined, 
    "Note example 2", 
    new Date(2020,6,2,15,30,0,0,0),
    new Date(2020,6,2,15,45,0,0,0),
    {
        calendarId: "1",
        firstReminderMinutes: null,
        recurrence: "daily",
        recurrenceInterval: 1
    }
)

// delete one of the recurring events
await this.calendar.deleteEvent(
    "Title example",  
    undefined, 
    "Note example", 
    new Date(2020,6,1,18,30,0,0,0),
    new Date(2020,6,1,18,45,0,0,0)
)

Error:

I let the user pick out a target calendar where the events will be saved. If the user picks the calendar associated with the gmail account, it works as expected.

If the user picks the "phone calendar/device calendar/my calendar" (which is provided by many devices per default), the recurring entry that I don't even edit is cut off after a seemingly random number of days in the native calendar after I delete the other event. When I examine the event in the native calendar, it still says it runs forever (or until an end date if set), but it won't be displayed after a random day (usually around 1-3 weeks after the start is the last occurrence). The same happens when using deleteEventById. Non-recurring events work fine in both calendar types and iOS works fine too.

Here's the overview of devices and calendar types, where I tested if deleting recurring events work (yes if it works, no if the error above occurs). As described above, the gmail account is the calendar associated with a gmail address and phone calendar is a calendar provided by the device by default.

Device	Android Version	Gmail Account	Phone Calendar
Huawei P20 lite	9	yes	no
Huawei Y6	9	yes	no
Samsung Galaxy S8	8.0.0	no	no
Nexus 5X	8.1	yes	doesn't exist
Pixel XL	10	yes	doesn't exist
Samsung Galaxy J5	5.1.1	yes	no

I am using version 5.1.5 of the plugin and 4.14.0 of @ionic-native/calendar. The output running ionic info is:
