68Do11ars, you were using a pretty old version of PSReadLine (2.0.0-beta2 or prior), and it's likely that the issue was fixed in a newer version.
Please upgrade to the 2.3.5 version of PSReadLine from PowerShell Gallery.
See the upgrading section for instructions. Please let us know if you run into the same issue with the latest version.
