BQ24295: Low amperage delivery to battery.

Part Number: BQ24295

Tool/software:

Good day,

I am currently designing a module that will be used in subsequent 3v3 devices using the bq24295 as the power management IC. This is my first time doing so please bear with me Joy.

I am currently experiencing an issue where lower than expected current is being delivered to my battery:
Programmed 2A using RILIM -> Delivers only 700 mA. (Read using series multimeter).
Readings are usually at 700mA but upon changing multiple different power supplies, the highest ive achieved was 700mA.

I have also confirmed that the power delivery is indeed below the programmed amount by using a timing method as well as shunt in case the multimeter affected the charging.

Here are the logs for the I2C registers on the board for when the battery voltage was at 3.5V.
Additionally, I have bypassed the battery's PCM as I have read that could be a culprit for these kinds of errors.

I would also like to emphasize that this is my first time building a charging circuit so I could potentially have a hardware issue. I have attached my schematic as well as BOM so that the issue may be diagnosed.
