I believe the same issue is experienced by another user here: https://community.plotly.com/t/rangebreaks-with-bounds-and-values-show-overlapping-candlesticks/46067

code to reproduce this:
(example.pkl can be found on https://repl.it/join/pdmlylnv-angstscheisse )

import pandas as pd
import plotly.graph_objects as go

df = pd.read_pickle('example.pkl')

fig = go.Figure(data=[go.Candlestick(x=df['time'], open=df['open'], high=df['high'], low=df['low'], close=df['close'])])

fig.update_xaxes(
    rangebreaks=[
        dict(bounds=[15, 9], pattern="hour"),
        # dict(bounds=["sat", "mon"]),
        dict(values=["2020-12-25"])
    ]
)
fig.show()

Research direction

Start by running the Python reproduction with example.pkl and the Candlestick figure using the two rangebreaks shown. Trace how rangebreaks and candlestick x-values are handled together. Done means the reproduced chart no longer has overlapping y-values or candlesticks when the hourly and date-value breaks are applied.
