Minecraft Java and Bedrock Edition appearing to buy again

What I Expected to Happen Was ...:

I would expect this bug to disappear, because I don't need to buy another minecraft that I already have

What currently Happened was ...:

Every time I close and open Launcher, he asks me to buy or put a nickname I already have in my normal account, I already have the minecraft in my account already, only on the site and Launcher says I need to buy EVERY TIME.

Steps to reproduce:
1. I open Launcher to play Minecraft (usually I play the Java version)
2. I try to click to play, but asks to buy (and I have already bought a year in my account)
3. I renounce or uninstall and install Launcher again.
4. The option of playing and with you appears.
5. When I close and open it again, the same problem comes back.
