The CSDA vs Energy Web-Tool seems to give out weird ranges depending on E_start E_end and Axis-Setting

We noticed the following beaviour for protons in water at the CSDA vs. Energy tool on the libamtrack Web Version:
When looking at a logarithmic X-Axis and a linear Y-Axis the two curves overlap and look as I would expect it for a CSDA in Water vs Energy plot.

However when I switch the scale to linear X- and Y-Axis, the two curves do not overlap anymore and the CSDA ranges do not match the PSTAR tables (around 23cm for 500MeV protons).

When looking at data from 400 to 500 MeV, the curves also do not overlap and sometimes form something like a step.

I assumed that the tool should give out a plot for CSDA ranges for protons with energies between E_Start and E_End. Therefore I thought that E_Start and E_End just define the plotting region and should not change the proton ranges.

Thanks and best regards!

Working on it, I need to debug the wrapper for https://github.com/libamtrack/library/blob/eb0c5b963b2aaaab2f71d296b348265cf3c453a9/include/AT_DataRange.h#L95-L100
