Promotion series S1 -> G5 expired after 3 days???

Was in my promo series to Gold V with 2 wins and 2 losses. The last game I played was a win which was about 1 hour ago. I just logged back in to play the final game and was hit with a message saying my promo series had expired. It has only been 3 days since I got into the promo series and 3 days seems ridiculous.

Riot support website also says promo series below Gold 1 dont expire so im really confused. https://support.riotgames.com/hc/en-us/articles/204010760-Ranked-Play-FAQ#h2q2

I just wanted to play my last game but now I cant... Anyone else experiences this before or has any information about this kind of situation???
