HALion 5.1 udpate available

My 5.1 update installed without any problems, but I noticed something else though.

The envelopes on some of my custom made sounds aren’t playing correctly.
Particularly the more complicated / multiple node envelopes.

After the update there seems to be extra nodes which I did not add (even among my stored preset envelopes). Also, the envelope doesn’t play through to the end. The sound just drops to silence after the first few nodes.

I tried moving the nodes around to see if the plugin just needs to “re-register” the values, but nothing is helping so far.

Currently the only solution seems to be manually recreating all my envelopes, which I’m not keen on.

Has anyone had this experience and is there a solution?
