Inverted nipple piercing hole

Hi all,

I've had my inverted nipples pierced about 9 months ago. The healing was perfect, the crusties were gone in a month or so. Recently I've started to notice that the bar of the piercing is visible through a tiny hole in the middle of my nipple. Have any of you had this happen to you? Is it migration/rejection or could it be a temporary issue that's common for inverted nipples, as the skin in the middle is indented/thinner? My piercing salon is closed atm because of covid, so would appreciate any help.
