My iphone's Hebrew calendar has a bug

My iphone's Calendar app shows the Hebrew calendar as well as the Gregorian. This year happens to be relatively rare in the Hebrew calendar, in which the first day of Passover fell on a Sunday (April 13th, a few days ago) and this coming Rosh Hashanah will fall on a Tuesday (September 23, 2025). I read somewhere that this circumstance (Passover begins on Sunday, and the following Rosh Hashanah begins on Tuesday) won't repeat until the mid-2040's, about 20 years from now. I checked my iphone's calendar to see when exactly this would be. It told me that it'll happen again in 2045, when the first day of Passover will be Sunday April 2nd and Rosh Hashanah will be Tuesday September 12th. So far so good. But the problem is that the iphone Calendar app says that it will happen again the very next year, with Passover starting on Sunday April 22nd and Rosh Hashanah falling on Tuesday October 2nd. This is not possible. In the Hebrew calendar, there cannot be two consecutive years in which Rosh Hashanah falls on Tuesday. The correct date for Rosh Hashanah in 2046 will be Monday October 1st. I have confirmed this on two websites, hebcal.com and chabad.org. The iphone appears to get back on track in 2047, when it has Rosh Hashanah falling on Saturday, September 21st, which is the correct date. But the error doesn't inspire confidence in the iphone's Hebrew calendar.
