paket install breaks the build

Description

after adding a new dotnet core fsproj to my project and running a paket install the build for all dotnet core projects fails. The error message I'm getting is:

error MSB4184: The expression ""System.String[]".GetValue(4)" cannot be evaluated. Index was outside the bounds of the array. [/Users/kdummann/source/rubecula/frontend/frontend/birdvoices.fsproj]

I see a single file change in the .paket/Paket.Restore.targets files which seems to cause it:

--- a/.paket/Paket.Restore.targets
+++ b/.paket/Paket.Restore.targets

Reverting this changes make the build work again for all existing projects.

Paket version 5.128.6
DotNet SDK Version: 2.0.0 (I know it is outdated but I can't update at the moment because there a problems with other packages when I do that.)

Inspect the generated .paket/Paket.Restore.targets file and reproduce the failure with Paket 5.128.6 and .NET SDK 2.0.0 after adding a dotnet core fsproj. Compare the generated PaketReferencesFileLines handling with the reported change, then verify that all existing dotnet core projects build without the MSBuild array-bounds error.
