Hi @slettengmats,
Welcome to RStudio! To help us answer your question, could you post some sample data in "reproducible example" format? Here's an article that explains how to do this:

FAQ: What's a reproducible example (`reprex`) and how do I create one? meta

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it and feel your pain. Then, hopefully, folks can more easily provide a solution. What's in a Reproducible Example? Parts of a reproducible example: background information - Describe what you are trying to do. What have you already done? complete set up - include any library() calls and data to reproduce your issue. data for a reprex: Here's a discussion on setting up data for a reprex make it run - include the minimal code required to reproduce your error on the data…

Even if your actual data is hard to include, confidential, etc., it would be really helpful if you could post just a few lines of a fake dataset so that we can help figure out the answer to your question.

Thanks!
