Relic pieces Slice a Bundle not fully working on webstore

I want to buy the slice a bundle ingame rn that gives relic mats and signal data.I went on to the webstore to try and buy it for just the signal data however only five of the relic mats are available on the webstore version with no signal data available.I have asked others about this and they have shown me that they can purchase the full bundle including the signal data.However they were on the American version of the webstore while i was on the European version so it may only be a problem with the European webstore.
