All the values are concatenated to one long string

[baskialdensys]

Here is the .env-Sample file content
InstrumentationKey = ""
ConnectionStrings__Db1Connection = ""
ConnectionStrings__Db2Connection = ""

after the transformation .env file contains this value , all the new line characters are gone and everything is combined in to one long string.
InstrumentationKey =testConnectionStrings__Db1Connection =constringConnectionStrings__Db2Connection=constring

Please advise.
