why does it switch to scala 2.11 when my code is all on scala version 2.13

[sawanverma]

When I included
// In project/plugins.sbt
addSbtPlugin("ch.epfl.scala" % "sbt-github-dependency-submission" % "3.1.0")

and then ran githubGenerateSnapshot,

first it was checking for all the dependencies for scala_2.13 then it switched to scala_2.11. Why so?
