I thought there was already an opened Issue about this, but I searched and I found nothing.
The bug is that just like in older versions of Mcreator recipe output reset to 1 when editing or exporting/importing workspace, block tick rate resets to 10.
This is not very important, but still very annoying. I hope you will fix it in 1.8.1.
(This bug was here from a long time, even before the recipe output bug was fixed if I remember well, so this is not a 1.8.0 exclusive bug)
