video effects adjustments, nothing happens

[n424]

While in Video Event FX, nothing happens after adjustments are made. Multicam editing is off.
Trimmer and Preview windows remain unchanged after applying adjustments.

First, check the status of the Split Screen View button as per section 1 in the link above.
Then if that does not solve your issue, you may have the conflict described in section 2.
If that applies, try updating your Nvidia driver to version 399.07 or later.

Also, assure of course that you're not missing something obvious. Make sure, for instance, that the playhead is actually over the event you're adding the effect to!

Can you post a screen capture of what you're doing so we can have a look?
