The windows are south-facing and the expansion of the filler doesn't match the wood. It means the repairs have cracked and have either fallen out or the paint has broken.
What is the correct product for filling and fixing?
There are a few 2 part epoxy resins made for this purpose. My preference is DryFlex from Repaircare. Cost of entry to the 'system' is quite expensive, if you plan on doing this kind of work again in the future it is worthwhile and the epoxy resins lasts at least a couple of years in an open tube.
