Hi guys,
Using Spine v3.4.02.
Not used Spine in a while and have been setting up some animations in the last couple of days.
Everything was going fine until earlier, when Spine suddenly stopped interpolating between my Translate keyframes, and a dashed line has started showing up on the dopesheet when I move a bone and key it, like so:

Now the animation seems to be in "stepped" mode or something, where the keyframe jumps to the new bone position at each frame, rather than smoothly interpolating between them.
In the example in the pic, the first and last keys are at x: 0, the middle blue keyframe is at something like x: 16.
When playing it back the bone stays at x: 0, changes to x: 16 at the middle keyframe only, then jumps back to x: 0 again.
Ideally it would smoothly interpolate from 0 > 16 > 0 across all frames, which is how it usually worked.
This jumping didn't happen when the interpolation worked earlier, so I assume I may have inadvertently pressed a shortcut key as I have not changed any options manually using the mouse.
Other animations in the same skeleton also work fine, and I have checked the playback options and "Interpolate" is selected as it usually is by default.
I've scanned the docs and can't see anything obvious, nor find any info regarding dashed lines on the dopesheet .
Can anyone please tell me what I've done and how to fix it?
EDIT:
Creating a new animation seems to work normally again, but duplicating an existing animation causes this issue.
I have been duplicating to save time, and this has worked fine until now - is it possible I have changed a setting for a single animation somehow?
