Intermittent connection bqstudio with bq34z100 chip

I am having an issue with connecting to the bqstudio software with my bq34z100 chip. I'm using the circuit recommended on the datasheet and I'm having an issue with having a constant connection and my address seems to be incorrect as well.

The address for the auto-connected device is 0100_0_06 and sometimes 0000_0_06 and I'm told that it must be 0100_0_16, which makes sense since I'm using the 0100_0_16-bq34z100G1.bqz file. When I get to the main page, I leave the auto-refresh on, and I can read some values like temperature and I can see the device and fuel icons light up and I can see "bq34z100" by the chip icon, and then it kicks me off and the icons disappear and after a few seconds and then the Target Selection Wizard pops back up and I start all over again.

I've also tried to program the chip with the new firmware, but I'm not sure if I'm getting through because I keep losing connection, so that could possibly be an issue, but it wouldn't seem to make sense why I keep getting the wrong address...

I'm using the EV2300 v 3.1m where I was told that the most recent update it v 3.1r, could it be that my EV2300 is not up to date?

thanks in advance!
