I'm running Backtrader for the first time and am having this issue when running cerebro.plot():

AttributeError: 'RRuleLocator' object has no attribute 'set_view_interval'
I've tried looking into RRuleLocator but there's very little documentation about this online. Previously, I was running into this issue ImportError Cannot import name 'warnings' from 'matplotlib.dates and solved it by git cloning from this repo https://github.com/mementum/backtrader. Any thoughts?
I tried getting rid of these lines and then installing backtrader, but that results in a plot like this (all jumbled up):enter image description here
