Colors are not shown correclty

When I apply color to an object, applied color are not correct, less saturated and less bright, I checked if smth wrong with layer settings, everything is default. One exception though, colors are like that only in that particular file, when I create a new canvas, colors are working as it should be. That file with color bug was exported as vectornator file, then I reinstalled vectornator(I was hoping that its hoing to solve my other bug issues). After reinstallation there is a color bug on that file.
When I export file to jpg, colors are are correct, so it is an issue when I actually draw in this file in vectornator

Can you check: maybe you have “View/CMYK Preview” mode enabled? As symptoms sound like that…
