Using a Custom Column hides other columns when you move these around

When asking a question, and using a custom column, this works well until you then move your columns 'around' when you move the column, Metabase then auto hides other columns and I'm not able to work out 'why'.

Question:

Custom Column

Result

Moving Column

Page reloads and items hidden automatically

What is the logic of these columns being 'auto hidden'?

what's the metabase version you're using?

You're on version v0.48.2

It happens on You're on version v0.48.2 as well

I'm experiencing the same issue? Any suggestions would be helpful.
