I cannot redeem a Java account using my Bedrock account

In the Minecraft Bedrock Loading Screen, I saw an announcment that I could redeem a new Minecraft Java account if I already had a Bedrock one. I clicked on the link and used the wrong account by accident. Later, I used the same link and used the correct account to redeem my Java version. It doesn't have the button that says "Get." Instead, I have to buy a new Java account, but I look all over the internet, and nobody has the same problem as me. Please fix this bug quickly, it is really frustrating.
