Pi Grove board doesn't pass I2C

I have several I2C devices attached to the Grove Base Hat including a AM2315 temperature sensor but the I2C device isn’t showing up in a i2cdetect scan. It works OK when connected to the GPIO pins but not through a Grove connector to the hat. How can I correct this?

Make sure that you used correct grove port, also check the grove cable continuity.

I’ve used each of the I2C ports and several different Grove cables. The Grove board does recognize the Human Presence sensor but not the AM2315.
