[Credit image block] align image credit block issue

[brm-ryd]

Hi,

Apologize for using english (i cant speak / write in Portuguese language) - just wondering about issue credit image block when align picture/photo its always set as Center, even in editor set as align right/left by result publish always keep in center default.
Does above issue related with below code in style.css of themes directory ?

.aligncenter {
  clear: both;
  display: block;
  margin-left: auto; /* does this can make the position become stretch ? i think yes */
  margin-right: auto; /* does this can make the position become stretch ? i think yes */
}

.entry .entry-content .wp-block-image img {
  display: block;    /* this should be okay i believe */
}

.entry .entry-content .wp-block-image .aligncenter {
  margin: 0 auto;   /* this i dont know whether to center element only (which not affect the image or otherwise it will force the align to center) */
}
