		| Abstract: | 
		A thorough investigation of the OGLE-IV Galactic bulge data (Soszynski et al. 2014) is performed, in order to test whether the weakening/disappearance of the phase modulation in Oosterhoff type-II stars, which was supposed to be detected in M3 (Jurcsik 2019), is a general property of the Blazhko modulation. |
