What is the Sharia ruling regarding the situation of a wife who was divorced by her husband with one irrevocable divorce in absentia, followed by a revocable divorce four months later, knowing that their marriage lasted for one year and three months and they only lived together for two weeks?

The wife's absence has no bearing on the occurrence of divorce; what matters is the husband's pronouncement of it. If the husband divorces her with a single pronouncement, it is not an irrevocable divorce unless it was before consummation or khalwa (private seclusion). If he says, "I divorce you with a single, irrevocable pronouncement," it counts as one divorce, and he can take her back before her iddah (waiting period) expires. If he had taken her back into his marital bond before the iddah expired, then the second divorce is valid. However, if he did not take her back and her iddah expired, then the second divorce is not valid because she is no longer his wife. It is advisable to consult Sharia courts or Islamic centers and speak directly with scholars.
