---                                                     ------------------  
https://site1.com                                             15   
https://site2.com        

Answer 1

Actually, It's a strange behavior, Although the CompatibilityLevel is optional in the command of creating a New-SPSite. but in a case of this parameter is not specified, the CompatibilityLevel will default to the highest possible version for the web application depending on the CompatibilityRange setting.

Note: The CompatibilityLevel values can be either 14 for SharePoint Server 2010 sites or 15 for SharePoint Server 2013/2016 sites.

So the CompatibilityLevel must have a value that denote to the template version.

So the solution for such errors can't be predicted. Meanwhile, I suggest as a type of tracing to try to

• Create a new Site collection via PowerShell, close the PowerShell and reopen it again as administrator, then perform Get-SPsite and check if the CompatibilityLevel is displayed or not!!

• If CompatibilityLevel is not displayed, try to Create a new site collection via Central Administration then Open PowerSehll as Administrator and perform Get-SPSite and check if you got the same issue or not!
