Why is Phriction being kept on such a low priority? This task has been since 2014 if we take into account this: T5254: Allow top-level wiki doc to display entire document hierarchy instead of only 2 levels

I have found that I can rearrange all the columns in some projects but cannot do the same in another one. Here's a screenshot. Now, I am not sure if it is a bug or just a random error.

The rearrange dialogue box only shows a maximum of 5 columns although the project has more columns. This limits the ability of rearranging any column present beyond column number 5.
