Keyed Resolution only updates once, after that it does not update

[EDELVIZ_ARCH]

It seems like Vray only changes Keyed resolution settings once and then after that does not change them any more.

Steps:
1 Open this file: https://www.dropbox.com/sh/slahc1tio...OheDq79Ja?dl=0. In this file the several resolutions are keyed
2 Start RT
3 Resolution is correct
4 Change to another frame, the resolution of RT will update
5 change to another frame - now the resolution will NOT update any more

This same is true for VRay Standalone. This is a huge problem for rendering stills.
