Most damping issues seem to arise from positive real parts, so I wanted to check:
1- Do these minimal positive real parts indicate any concerns?
2- Are they essentially negligible in terms of impact on system stability?
I appreciate any guidance you can provide to improve my understanding of their significance in the analysis.

If it only arises from numerical errors, ignore it. If you have the impression that it may due to the behavior of the system, it indicates a tendency to instability.

Daniel Poelaert Thank you for the answer,
I think also it is an indication of a tendency toward instability since the mode decays with a very low damping ratio over time.
