Convolution cernel disappears

Hello!

I have an issue with a small detail, but a bit annoying one. When I open my scene, my bloom kernel looks correct, but after rendering it from sequencer it disappears and to bring it back I need to restart the engine. any idea why is it happening? Rendered images don’t have bloom kernel visible. I’ve also noticed that going full screen with f11 disables bloom too. very weird

Here are screenshots before and after:
