¨Export As¨ does not work saving either 2-Up or 4-Up Quality Anymore in Photoshop

Hello everyone! I am trying to see if someone else has the same problem I do.

I am using the latest version of Photoshop CC, constantly making the updates from Creative Cloud and since yesterday I am having this problem and I really do not know how to solve it. It´s the first time it´s happening for me. 

When trying to ¨Export As¨ my work created in Photoshop, on this case a simple banner design, I am trying to export it as a bigger quality ¨2-Up¨ and everything goes well showing me the file will be ¨6.79M¨ which is what I want. After saving and checking the exported file the size does not match and I am constantly seeing it in 218MB. Which is lowest than it showed me before. 

I tried it with Export As, Save As, tried saving it at 2-Up, then 4-Up - saved it as JPEG then as PNG and everything goes well inside Photoshop but whenever I check the file in my computer it was saved as much lower than it supposed to. I am attaching you a print screen on how it shows before saving and then what the file is after saving. Anyone else has this problem before? I would definitely appreciate any kind of suggestion and help as this is the first time this is happening for me and I am not sure on how to solve it. 

I even uninstalled Photoshop CC from my computer and installed it again in the hope that this will be solved and it is from my end, but it is the same as before. Restarted my computer, checked for Windows updates and made sure I am up to date from my end, but the problem is persisting. 

Thank you very much for taking time to read this! I appreciate it!
