Logic Pro 10.7.8 Recording midi on an auxiliary track of a multi-instrument deletes in cycle mode

Hi

Does anyone else have this problem in Logic Pro 10.7.8?

When recording midi on any auxiliary track of a multi-instrument the recording gets automatically deleted when you stop recording, click anywhere at all within Logic, or if cycle mode is switched on as soon as the playhead goes back to the beginning of the cycle.

I thought it might be a UVI Falcon issue, but I have got the same problem on a multi instrument version of Omnisphere.

Strangely, the same issue doesn't happen on the first track of the multi instrument, only on subsequent auxiliary tracks.

I hope that makes sense.

Thanks
