Help with DFR0265 with analog sensors not working

Hi all,
I just got this DFR0265 and I'm using it with an Arduino UNO WiFi Rev2.
Seems like analog ports A0 and A3 are not giving me results. I've tested it individually and get results back from all A1, A2, A4, and A5 but not those two. I also tried having 6 sensors connected from A0-A5 and the same thing both A0 and A3 don't give me any results. I thought maybe it's a power issue but I tried both 3.3 and 5V it still was the same. A0 and A3 just have values. When I disconnect and reconnect the sensors on A0 and A3 both analog ports give me jumbled characters as results. I tried swapping the sensor to see if my sensors were faulty but the soil moisture sensing works on other analog ports so it must be isolated to A0 and A3. Also if something is plugged into A4 both A4 and A5 will show results. Take a look at the attachment for an example.
Oh yea just a simple test of reading the analog values, all the analog ports have results, usually, a number from 100 to 250 but A0 is always value 0
Does anyone have any ideas what is going on? Thanks.

2021-01-15 18:53:48 Regarding this issue, I can only regret to tell you that these pins of your Arduino are broken. Under normal circumstances, these pins will not have any problems. The Arduino itself is designed like this. If you must use it All pins, you may need to change another Arduino
