Vultures disappear when moved (The Witcher 3: Wild Hunt)

sorry if such a topic has already been
In general, the situation is this: I put glyphs of recovery in gloves, pants and bots. And when moving between large locations (example of Wellen-Skelleg), glyphs disappear from the slots. When moving to one location, they do not disappear, but when moving to another location, the slots in the gear are empty again.
WTF?
