Need to shift some data values in columns to the right but others the same

Why is the work around not the solution ?

Additionally, I have a quibble with the way you posed your challenge;
If someone wished to use example data to test code against, they would type it out from your screenshot...

This is very unlikely to happen, and so it reduces the likelihood you will receive the help you desire.
Therefore please see this guide on how to reprex data. Key to this is use of either datapasta, or dput() to share your data as code
