Facing issues creating files in folders connected to a windows server.

So, basically ive got a new mac and i have connected it with a windows server 2019. I am facing issues with some .docx files in which if i paste/create a new file (docx or xlsx, etc) after editing it and saving or some time the file disappears from the folder and the other windows pcs also cannot see the new file. When i press cmd + **** + period the files reappear but are greyed out i cannot turn them back into the normal version.

This is really hindering my daily work, can someone please tell me how do get them back to normal?
