I have a set of values from -87 to 77 in my raster and I would like to group them into different categories. When I make the classes manually (picture on the left) and select apply, QGIS automatically changes them and groups them into new classes (picture on right). I have tried eveyrthing from reducing the upper and lower limits of classes based on the value range to updating QGIS, but nothing seems to work. Can someone please help me?
I am using QGIS version: 3.26.1.
