That's because lower ranked members cannot wear the signatures designed for higher ranked members since certain formatting like size and background is disabled until you hit the applicable rank.
I think Hhampuz is a very professional and fair manager so far. Two thing I haven't even seen while participating in some Hhampuz campaign and that are.
1. Never before had seen her accept participant of lower rank to fill higher slot.
2. Never before had seen him accept higher-ranked participant to fill lower slot.
This provide justice for all participant as their application will be considered according to the available slot.
