DOP seems broken?

DOP is giving me a processing error even when trying to pitch shift on this one clip of audio and I can’t figure out why - any ideas?

One thought I had was that maybe it’s because the name was too long. I shortened it in the Pool window and then the waveform disappeared and the region is now blank. In the following pic the clip to the left of it is the same (and you can see both in the pool) but neither of them plays audio now.

Is this user error or is something going wrong here? Is there any chance we could get an option to turn off DOP in the next update? Whenever I use it it’s only a matter of time before I come across something really goddamn weird. I’m stuck on N7 until there’s a way around this…
