Exr sequence not showing image in node (compositor)

Hi,

Update: my goal is to load 1 sequence of 600 frames in 2 image nodes. One loading frame 1-299, second loading frame 300-600. Somehow setting the number of frames to 300 causes the error of missing image. I now have made 2 seperate sequences to load, it works fine. But still, it should also be possible with 1 image sequence loaded in 2 nodes.

When I load exr sequence in image node (compositor) it often, not shows the current frame image in de node. Am I missing a setting? It seems to be the case for some random frames that have no image loaded. Anybody know why this is behaving as such?

Also I have enabled “auto-refresh” but this is not always working. Unconnect en reconnect a line usually works better.
