המהר"מ - Someone added him a father twice, with completely incorrect information-why???

For a reason I don't understand, the same person added a father twice (the information is completely wrong), changing my family tree
The correct information is according to the geni general tree
It should be noted that lately many people are building a tree parallel to the general tree (with completely incorrect data), causing the destruction of two years of work that I do
In the example here, the same person erects the same incorrect tree twice, and attaches it to the general tree, why
????
