[BUG]Set-PnPPage -Title property doesn't work properly

[Mengting233]

I am running a for each loop for the two items in the csv below.

When I refer Title to $Site.Fastighetnr the Title of the home page can be updated. But when I refer to $Site.SiteName the Title of the home pace cannot be updated. Is it because the site name has so many special texts?

Doesn't work:
Set-PnPPage -Identity "Home" -Title $Site.SiteName -LayoutType SingleWebPartAppPage -Publish:$true -CommentsEnabled:$false

Works:
Set-PnPPage -Identity "Home" -Title $Site.Fastighetnr -LayoutType SingleWebPartAppPage -Publish:$true -CommentsEnabled:$false

Works if I put the texts directly for -Title:
Set-PnPPage -Identity "Home" -Title "2809 - Kärra 26:5" -LayoutType SingleWebPartAppPage -Publish:$true -CommentsEnabled:$false

I copied the SiteName column and change the copied column name to "Title"

Now it works. I guess the SiteName column has problem in the csv.But I have refered $Site.SiteName in the Write-host, there is no problem.

Set-PnPPage -Identity "Home" -Title $Site.Title -LayoutType SingleWebPartAppPage -Publish:$true -CommentsEnabled:$false

Where $Site.SiteName Works:
Write-host "Site Template provisioning completed for $($Site.SiteName) - $($Site.URL)"! -f Green
