Bitbucket Pipeline Cloud step size bug?

[Bitwise DEVS]

We initially tried 4x step size in a parallel steps and it works, however after changing it back to 2x in an attempt to save build times and returning it once again to 4x due to realization that the build can no longer work with low spec environment. The step is now having error.

Configuration error

The size '4x' in your bitbucket-pipelines.yml file is outside the allowed range. Please specify either '1x' or '2x'.

I was able to rerun a 4x size step. Clearly this seems to be a bug.

This issue no longer happens after closing a PR and creating a new one. It seems that a push and merge on a branch with existing PR where it triggers a pipeline can cause the above issue.
