I have a Lightning report with two group by fields and various fields in the details. The report is producing the correct data but does not display correctly when using the Edge browser.
For example, assume the report groups on animals. If I have two kinds of animals - cats and dogs, there is a grouping for cat with details of different kinds of cats and a grouping for dog with details of different kinds of dogs. The details don't line up correctly. For example, on the screen a dog breed might show up next to the cat grouping. Also, the subtotal labels show up next to detail records instead of next to the subtotal values. You can see that the lines that should delineate a group and its details don't line up.
The difference in the line might seem insignificant, but it is really throwing off the report and is providing misleading information.
This doesn't happen to me when using Chrome or Firefox.
