I bought an 256 gb microsd card and i transferred all of my contents into this sd card without lossing anything. Problem is ux0 looks 231/238 gb i mean only 7 gb free space but in pc it looks 111 gb free space. How to fix this issue?

I bought from a trustworthy seller in my country. I didnt test btw but in comments buyers says "the card original dont worry about that" so i trusted them. I occured this issue before my newly bought ssd gone in a 11 months and i lost many things so im very careful about this. I add the images below. I fixed the problem. I just update my console then henlo is gone so reinstall henlo and put my back up into micro sd card. Now there is no problem.could be a fake SD card, format it and test it with hw2test to make sure its actually 256gb card
