looking for UX suggestions

just after some opinions on some UI. The UI is based on an existing system that is a windows desktop application converted to the web and it matches very close. The desktop version runs a scrollbox with frames in it. The new one uses divs in a table, the only problem is that I honestly dont like the look of it, its big and doesnt feel right. So looking for suggestions, its a little untidy, its incomplete but you get the idea.
