I don’t know if this is related, but since the 9.5 upgrade, when I Time Stretch a short section (sliced) of the original recording, Cubase overlays the edited short section over the original recording, so it’s stacked on top like an overdub. The original recording is also time stretched, just like the shorter part, so it’s not actually the “original” recording. It also introduces other time-stretch anomalies, so the whole thing just seems weird. I know I’m not helping solve your problem, but at least we know others are having similar types of issues. Good luck!
