There was a good reason why the change was made to the Sweep 1 rail component around version 8.25. However, it seems that this change has had a larger impact on various other types of files, so it was decided to roll back all of the code that was introduced and make the component behave as it did in version 8.24. So, with the release of 8.27 RC 1 (which should be released later this afternoon), the Sweep 1 rail component should behave as it did prior to these changes. We apologize for this inconvenience.
