With the LMDTOOLS version this didn't happen...
I configure the TLMDButton with 3 images from a List that I had already compiled in STUDIO 10.3 RIO and in this version STUDIO 12.2 doesn't save the number of icons and every time I open the project I have to put the 3 images back on all the Buttons because it appears configured with 3 NumGlyphs. This is a problem because I have to program with code in the OnShow events of all the forms so that at runtime the buttons are displayed correctly with 3 NumGlyphs.
