When the talismans are fully upgraded the auto buy shards is preventing the runes from buying fully even when there is thousands of rune levels affordable, the system is priortizing shards over runes despite there being no possible talisman upgraded available. I frequently have to manually turn off auto for shards in order for the runes to catch up. There should maybe be some prioritization logic to make runes the priority if talismans are full before buying more shards. See the attached screen recording. I do not know how to attach a save of my game since I upload them in the account tab for the cloud save but if there's some other way to give you the save file please let me know happy to do so.
I am playing on mobile on Android in the Chrome browser
