More than 2 systems on PortfolioMaker

If I add three systems to PortfolioMaker, whenever I change the percentage allocated to one system, the remaining percentage is automatically split evenly between the other two systems. This makes it impossible to allocate different percentages to all three systems.

For example, I want to split my capital among three systems and allocate 50%, 40% and 10%. When I enter 50% for the first system, the other two are automatically allocated 25% each. If I change the next system to 40%, the other two are allocated 30% each, etc.

It also seems that when 3+ systems are displayed in the chart, the colors of the lines do not match correctly to the colors in the table below.
