Problem with the history with prophet

[Reich3rKaese04]

Hello, i dont really unterstand how prophet get me this history.
So i have like 1600 data for prophet and if i do a forecast, Prophet give me my Forcast data and the history back. But the history doesnt match with my data i gave prophet. for example:
this is my data i gave Prophet
{
"von" : "2024-01-02T19:48:04",
"bis" : "2024-01-02T23:58:59",
"auszahlung" : 0.0,
"einzahlung" : 0.0
},
{
"von" : "2024-01-02T23:59:59",
"bis" : "2024-01-03T03:58:59",
"auszahlung" : 0.0,
"einzahlung" : 0.0
},

and for the same date i get
"auszahlung_Vorhersage": [
{
"start": "2024-01-02T19:48:04",
"end": "2024-01-02T23:48:04",
"yhat": -389.34131272431205,
"yhat_lower": -4346.522510337999,
"yhat_upper": 3310.4152206830386
},
{
"start": "2024-01-02T23:59:59",
"end": "2024-01-03T03:59:59",
"yhat": -98.38834393401203,
"yhat_lower": -3713.2561171727484,
"yhat_upper": 3460.333220606803
},
why is this? Because Prophet make a Forecast for the history data?
im thankfully for any help.
