BQ25504: Tina Ti's simulation error

I am now doing research with bq25504 EVM.

We are testing evm using a solar cell with a Vmpp value of 1.6V, an Impp value of 36mA, an open circuit voltage of 2.2V, and a short circuit current of 40mA. Therefore, the resistance value was changed to match this mpp value and the resistance value was changed so that the undervoltage was 3.6V and the overvoltage was 4.2V.

This evm was used to check the following measurements. Green is the vstore value and yellow is the vin value.

In order to know more about the measured values, I used the tina ti tool to check the simulation using all the values.

Since the vstore value is not 4.2V, the vbat value and the solar cell value have been modified to match the value initially provided in the tsc file of bq25504. Vbat was 4.7uF and solar cell value is Vc: 0.5V, Isc: 0.4mA, so it is 4.4 times to set Voc to 2.2V. To obtain the following graph.

The blue square of Vin in the graph above is 330mV, so it is in cold start mode, and the green square of Vstore is 2.4V, not 1.8V. Why? We also need to track the mpp in Vin, but we don't see that point. What is the reason for this? And I modified the values arbitrarily to identify the simulation that fits my measurements. If not, how do I modify the values to get a simulation similar to the measurements?
