Increasing the cycle number for Lithium ion capacity fade simulation

My name is Frank and I am graduate student new to using the Comsol software. I am currently having issues increasing the cycle number from 2000 cycles up to 4000 cycles for capacity fade of a Lithium ion battery, and would love to find any assistance at all I can get.
I am currently running a capacity fade simulation for 2000 cycles and have obtained my initial results.
I tried increasing the cycle number from 2000 cycles to 4000 cycles by editing the capacity fade parameter and changing the no of cycles from 2000 cycles to 4000 cycles, having a closer look at my graph for this number of cycles, I noticed an error in the result, the Relative capacity does not start from an initial 1C, but starts from 0.86C which cannot be correct.
Please find attached a comparison of my results for 2000 cycles and 4000 cycles.
