Scroll Wheel give error in custom container.

I am trying to design a custom container which has a scroll well. This scroll wheel item template has a wildcard. When I add a Scroll Wheel and generate code, compiler generates same variables three time in CustomContainerBase.hpp file. Like below;

 
 /*
 * Wildcard Buffers
 */
 static const uint16_t ELEMENTTEXT_SIZE = 5;
 touchgfx::Unicode::UnicodeChar ElementTextBuffer[ELEMENTTEXT_SIZE];
 static const uint16_t ELEMENTTEXT_SIZE = 5;
 touchgfx::Unicode::UnicodeChar ElementTextBuffer[ELEMENTTEXT_SIZE];
 static const uint16_t ELEMENTTEXT_SIZE = 5;
 touchgfx::Unicode::UnicodeChar ElementTextBuffer[ELEMENTTEXT_SIZE];

Because of that, compailer give error and I can't fix it. What can I do about that?

Thank you for help.
