INA260: ALERT is latching when configured for Transparent mode

Part Number: INA260

I am using the INA260 power monitor. Reading and writing to the device appears to be working fine. The issue I am having is with the ALERT pin.

The CONFIG reg is set to 0x6F27. So 1024 sample averaging at 1.1ms conversion time and MODE is continuous.
The MASK reg is set to 0x0400. Enable the Conversion Ready, ALERT polarity is active low and Alert Latch enable set to Transparent Mode.
The ALERT pin is tied to an interrupt on my microcontroller to trigger sample reading when the conversions are complete. No faults are being monitored (just conversion ready).

This all appears to work just fine. I am getting an interrupt every 2.25sec just as it is configured. However, I have to read the MASK reg in order to keep it working. Otherwise I get the first interrupt from the ALERT pin and it appears to be latched.

Based on the data sheet I understand that ALERT pin should go back to idle state on its own when the LEN bit is 0 in the CONFIG register.

Am I missing something with respect to the configuration or am I not understanding the operation correctly?
