Correcting spelling not constructive? edit

My previous edit on this page was rolled back with the following comment:

"Hello, I'm Serols. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Degenesis— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help Desk. Thanks. Serols (talk) 15:20, 10 September 2018 (UTC)"

I have no idea why correcting the spelling of a product title would be "not constructive". I also don't see in which way I have been "experimenting" by correcting it and putting a link behind it in line with other links from the same table. (I would understand if linking to a shop page were deemed undesirable, but that is neither a reason to reinstate the wrong spelling, nor to only revert my edit and let the other links to the same page stand.)

I also note that that this rollback has been made using a tool named Hobble, which is intended to fight vadalism. While I am not an experienced editor, I know that my edit, even if it had been in error (which it isn't), has nothing to do with vandalism whatsoever.

I am undoing that rollback now. I have a copy of that book right in front of me, and its title is consistently spelled KatharSys, not Catharsis. It also takes about 5 seconds on the net to find a plethora of sources using the correct title. -Andreas
