Get-PNPTerm and Set-PNPTerm are not working

[Coyotebd]

When I run:

get-pnpterm -TermSet "MyTermSet" -TermGroup "MyTermGroup | select name,isdeprecated

It works as expected
If I run

get-pnpterm -identify "GUID" | select name,isdeprecated

It finds the term, but isdeprecated is blank, as are a number of other fields. In this case the GUID I'm using was found by running get-pnpterm to find the GUID of the term I want to change.

Additionally, when I run

set-pnpterm -identify "GUID" -deprecate $true

I get the error:
Set-PnPTerm: Object reference not set to an instance of an object.

I've attached two txt files. Missing.txt is what I get when I search by the GUID. Full.txt is what I get when I list all terms in the group/set and then filter it by the GUID

Get-Pnpterm -Identity $theTerm | select * | out-file -FilePath c:\temp\missing.txt
Get-Pnpterm -TermSet "Projects" -TermGroup "Projects" | ?{$_.id -eq $theTerm} | select * | out-file -FilePath c:\temp\full.txt

full.txt
missing.txt
