All of the above alerts are caused by shading of the high-pressure cell.

Short contacts are expected at high-pressure (see full text).

Sadabs corrects for all systematic errors that lead to disparities in the
intensities of symmetry-equivalent data. These may include absorption by the
mount, crystal decay etc.  Here, residual absorption errors from the pressure
cell are an obvious source of further systematic error.

The use of restraints in the refinement mean that off diagonal terms in the
variance-covariance matrix are significant, and the diagonal approximation
used in Platon/Checkcif is badly in error.
