My minecraft's version it dosen't work Right

Good day!
In the time that I have the game in possession, I cannot have the full Minecraft experience, In this case I started with the trial version to verify that my PC would not get too hot when using the game ... In the end I agreed and continued to buy the same one without doing some kind of Re-installation or something like that ... just buy the Trial version and when I bought it I just kept running the game normally.

From here I NEVER skipped the research tree ... the way the game draws a box saying (DIAMONDS!) Etc, the effects both beneficial and harmful do not come out correctly with the time marked in my monitor (Venom 1:00 etc) only comes out one drawing and I have to wait for it to be removed ... it does not say what it is or how long it lasts ...
In addition, the Commands I cannot corroborate that they are applied correctly in this case I only corroborate that I can manipulate things like the weather or climate ... when they are enchantments or things as common as / kill (@a) it tells me that it is not specified, also the Redstone does not work correctly just try to perform a common clock and the whole redstone turns on at the same time without intervals, The same achievements of the game that unlock additional appearances does not advance in any way (Although I have already played several hours ). For my part I would think that it just seems that I do not buy the game but I can play normally and I can connect to Ryalms or servers. In any case, I hope you can support me to corroborate what is happening ... and how I can solve it ...
If you tell me that it is only a matter of Deintestinal and Reinstall the game I would like to know that I do not have to buy the title again to play again.
(It should be noted that I made a creative copy of my world so that I could show the points said)
Thank you! <3
