Missclicks after MT5 to MT4 EA conversion with graphical user interface (with BitmapLabelCreate)

I created Indicator/EA for MT5 and it works fine. The problem occured when i converted it to MT4. I used same exact libraries that i used for MT5 versions like:

a) MT5 - https://www.mql5.com/en/docs/constants/objectconstants/enum_object/obj_bitmap_label

b) MT4 - https://docs.mql4.com/constants/objectconstants/enum_object/obj_bitmap_label

MT5 code fragment for button creation:

StringConcatenate(nazwa_w, numer_buttona, "button_text_", i1);
BitmapLabelCreate(0,nazwa_w,0,poz_x+(0.25*((32*gfx_multi)/div))+(i1*((16*gfx_multi)/div)),poz_y+(0.125*((32*gfx_multi)/div)),nazwa_plik_inv,nazwa_plik,((16*gfx_multi)/div),((24*gfx_multi)/div),numer_fonta*((16*gfx_multi)/div),(nr_koloru*((24*gfx_multi)/div)),clicked_copy,CORNER_LEFT_UPPER,ANCHOR_LEFT_UPPER,clrRed,STYLE_SOLID,1,false,false,false,1);

MT5 code for button click press check:

      bool returned_click = false;
      for(int i1 = 0; i1<dlugosc_nazwy ; i1++ ) {
         StringConcatenate(nazwa_w, numer_buttona, "button_text_", i1);
         testint=ObjectGetInteger(0,nazwa_w,OBJPROP_STATE,0);
         if(testint==true) {
            returned_click = true;
         }
      }   

MT4 version for button creation:

nazwa_w = StringConcatenate(numer_buttona, "button_text_", i1);
BitmapLabelCreate(0,nazwa_w,0,poz_x+(0.25*((32*gfx_multi)/div))+(i1*((16*gfx_multi)/div)),poz_y+(0.125*((32*gfx_multi)/div)),nazwa_plik_inv,nazwa_plik,((16*gfx_multi)/div),((24*gfx_multi)/div),numer_fonta*((16*gfx_multi)/div),(nr_koloru*((24*gfx_multi)/div)),clicked_copy,CORNER_LEFT_UPPER,ANCHOR_LEFT_UPPER,clrRed,STYLE_SOLID,1,false,false,false,1);

MT4 version checking the click:

      bool returned_click = false;
      for(int i1 = 0; i1<dlugosc_nazwy ; i1++ ) {
         nazwa_w = StringConcatenate(numer_buttona, "button_text_", i1);
         testint=ObjectGetInteger(0,nazwa_w,OBJPROP_STATE,0);
         if(testint==true) {
            returned_click = true;
         }
      }   

As you can see they are almost exactly the same, but the SringConcatenate yet the results in MT4 version are crazy.

Only first 2 buttons work as they should, others - see for yourself on the movie: (even clicking outside any button activates them)
