Wardrobes - sizes
There a few things to understand about changing sizes.
You can change any sizes with red arrowheads and, once you have set a red arrow size, it will not change (unless you remove the feature and then bring it back).
Drag the arrow forward (the way it's pointing) to increase the size and backwards to decrease it, or type the size into the box and press the tick. Sometimes this appears to be back-to-front, but just carry on and you will see if it is correct.
Sizes with two grey arrowheads can change, but not directly, as they are the result of other adjustable (red arrow) sizes. Bear in mind that sometimes the other sizes may not be in the same view. For instance, you can set the overall height of a wardrobe box and the height between all the shelves except the top one, which will be shown in grey because it is the result of all the other sizes.
There are constructional limits on some sizes. For instance, you can't have a box over 3000mm high or over 1180mm wide. In such cases the arrow won't move beyond the limit.
Always check the grey sizes to see that they are what you want. If you need them to be different you will have to alter an associated red size.
