leaking tap

I have an older deva mixer tap in my kitchen. I have replaced the cartridges over the years because they have leaked. However, the problem I am having now is I have tried to buy a number of cartridges but the spline will not fit inside the tap lever. Although the spline is 8mm the new splines are not cut so deep so will not fit. the splines are cut too shallow. This cartridge looks as though the spline cutout depth is more defined. Are you aware that some splines are deeper cut than others? Are you able to help me, please?

The above link is for a Deva cartridge which looks like yours.

The link that you came from is a Crosswater cartridge.
