Import-CSV Looks in Parent Directory

After throwing an error using ConvertFrom-String, Import-Csv no longer uses the current directory, but looks in the parent directory instead. I'll add my code so you may simulate the same thing. This code throws an error on ConvertFrom-String, which appears to generate the directory issue on the Import-Csv, but not other cmdlets like Get-Item or Get-Content.

$PSVersionTable:

Steps to Reproduce

Code:

$imp = Import-Csv .\TestColumn.csv
$Template = @'
{Type*:IP4Address},{IP:10.20.30.40}
'@
$imp.col2 | ConvertFrom-String -TemplateContent $Template -PropertyNames Type,IP
Import-Csv `.\TestColumn.csv

Content in the IP file (fake IPs... of course)

gc .\TestColumn.csv
Col1,Col2
One,@{IP4Address=10.20.30.41}
Two,@{IP4Address=10.20.30.42}
Three,@{IP4Address=10.20.30.43}
Four,@{IP4Address=10.20.30.44}
