Visual Scripting Tool - Can't nand/or/nor/or function parameters

In the visual scripting tool one can not use multiple function parameters as input in the same logical operation. On build the tool thows the following exception:

2020-10-25 00:55:30.479 - Thread:   1 ->  Error occured during the graph reconstruction: System.ArgumentException: An item with the same key has already been added.

Also, why is there no And-Gate? Under logical functions?
