Powerpoint export not using "current values"

example in question:

the default setting for this report is 12 months, which shows the latest month in the calendar visual and in the title

we want to show as of last month so I set the month filter to all months except for october.

now September is showing in the calendar and the page title also says September.  This carries through to the rest of the pages of the report as it is a filter in Filters on All Pages.

I then go to export, powerpoint, and embed an image

and choose the default options of Current Values

the result in the exported powerpoint is

as if I had chosen to use "Default Values" instead of "Current Values".  Choosing "Default Values" gives the same results so the options are not just swapped.  The only thing that works is to edit the report in the workspace; set and save the filter options (thus making them the default values); and exporting them their or updating the app the report appears in and using it there.  This is not an acceptable solution as the users need to be able to export their filtered reports themselves without having to access the report in the workspace.

I have tested this on other reports and had the same behavior.  This has happened in the past few weeks.
