[BUG] Total performance calculation wrong - seems to calculate old holdings

[viktor-sc]

Bug Description

For one specific stock I had one buy and sell in the past. Later I bought it again twice and then the price went down.
The total performance shows -248% which can't be right. In fact it's about -76% for the current holdings. The one in the past somehow affect the calculation.

To Reproduce

I attache an short export to reproduce:

ghostfolio-export-PSM.DE-202405151944.json

Expected behavior

As the 8 stocks from the past were sold long time ago they should not affect the performance in my opinion. At least it should not be compared to the current price...
