I have a problem using group layer. When I use a single layer, I can see the image returned by wmts correctly, but after I add the layer to the layergroup, it will only be displayed at certain levels of zoom, such as less than or equal to 8, and the rest will return 400, with a similar error message. : Column 210 is out of range, min: 213 max: 214, etc., beyond the boundary, but the same boundary is requested normally in a single layer preview，Is there something wrong with my configuration?
