bug in StartAllBack - one of several menu names is not showing

[Kuifje2]

Using StartAllBack 3.8.13.

Using segmented view of the taskbar.

I have 4 menus added to the taskbar: Desktop + 3 other folders. "Bureaublad" = "Desktop" in Dutch.
StartAllBack shows the double-arrow indicator for all 4 menus and all 4 menus work properly --> OK
But StartAllBack shows the names of only 3 of the 4 menus. The name for the leftmost menu is not showing --> UNEXPECTED. See image below.

This happens only on the segmented view (which I prefer).

The starry-blue area on the bottom left is my desktop image.
