Bar chart on OpenSearch is visually cutting off last day of data from

I have implemented a bar chart to monitor product usage (email opens (opens) and link clicks within those emails (clicks)).

I am finding a strange bug where sometimes it would cut off the opens at the end of the visualization for example if end date is set to the 22nd of Dec will cut off not showing the bar for opens for that day and if end date is set to the 23rd instead will cut off opens (but in this case would show up for the 22nd).

There doesn't seem to be anything on OpenSearch that shows how to stop or fix this problem.
