Chart or ram and krishan real?

Why can't I find the exact birth chart of Lord Ram and Krishna as said on the internet? I put in the time and date that they say 12.30 p.m. 12th of January 5114 BC on Kala software which seems to go that far but the chart which comes up at the time isn't the same as depicted and taught with. Also neither is the same with Krishna. I tried to tweak it up and down in here due to the conversation of the BCE and I also tried doing other things but the chart isn't the same and I can't seem to find that time. So did that even actually happen or are the gods and their chart just symbological?
