Yes, the bug is still there but it will be fixed in future releases. This time I'm attaching a project
with custom style that you can set to your numerics to override their "MinWidth". The numbers disappear because the PickerTextBox
used in the Numerics has default MinWidth
that does not allow it to show properly on numeric size of 70. The attached style is for the default Office_Black theme but the theme changes for the other themes are similar to this one. You can find the modifications if you search for the words "" in the main xaml.
All the best,
the Telerik team
