When I place a break node for a custom struct then it looks as expected. However after reloading project one of variable’s name is changed to something unsightly:
On top is a break node placed earlier, on bottom is a freshly created one. only special thing about Uniform Scale is that it was added only recently (rest was created several engine versions earlier) and it was moved from bottom to above Delay variable.
