575 League of Legend RP option is gone, will it be back?

I grind points to redeem vp for Valorant. I've always redeemed the 575 option instead of 100. There were times when the 575 would be out of stock, but for that it usually says currently unavailable, to which I just save my points until it's restocked and then I redeem the points. However, the points were unavailable when I went to redeem them 2 days ago so I thought I would wait a few days. Today I went to check and the entire option for 575 is gone instead of saying unavailable, the only option available is the 100 rp. I did not encounter this before.

What I'm asking is, will the 575 rp be restocked as it usually does or is the option gone permanently or for as long as Microsoft wants? I do not want to redeem the 100 rp, but if 575 is not coming back I have no other reason to save the points and would rather spend it on the 100 rp instead of this being unavailable too.
