Anybody having inventory display issues?

Hey all, I only sell a couple of items on FBA, but I saw that yesterday one item that I had 90~ units in stock, started displaying as 0 inventory. I can still go to the listing and it shows as availablae for purchase. I also show I had sales of this item yesterday.

Today, my highest volume product is now showing the same. 0 units in stock, despite having over 1,800. Also had very active sales today.

Anyone else sharing this experience?

TIA!
