There is one condition set for this puzzle and it is there to keep the N-terminal end of the protein closer to the native (as you will see when we release this as a Quest to the Native). It shouldn't be too strict so you should still have the freedom to move the end of the protein, but it will not be very useful if you click on the checkbox next to "Show" under the Conditions Tab (below your score).
This problem has already been fixed and will be in the next update.
