Incorrect Transparency Blending Space

[gabrielac50655922]

Hello. I need to export my document to the internet in the correct color mode RGB.

I have all my colors in the swatches panel in RGB, as well as my images, and the Transparency Blending Space also in RGB, even in Document Settings I have set "Web". But with everything correct, the Preflight panel tells me "The transparency blending space is incorrect." So, having everything in RGB, if I set the "Transparency Blending Space" to CMYK, the error disappears.
Why is this happening?
I have other documents that are not so clean in color, that do not show that error. What else should I pay attention to for to not have error?

Export s PDF interactive. This is a RGB PDF and convets everythins to sRGB.

Or choose RGB PDF output profile from the PDF print section.

Yes, there is actually no color difference when exporting as an interactive PDF, everything looks fine and I know it is fine, I have tried it. I'm just worried that the error will appear. Why does Indesign insist there is a bug?
