Hello Mike,
We had a similar after immediately after having our lanai glassed in. Installers came back out 3 separate times and were never able to find how the leak came in even though it was only in one spot when rain, or water directly aimed in that specific spot with a hose on sprinkle for more than 5 minutes.
In frustration I decided I had nothing to lose by spreading 2 coats Flex Seal liquid in white on all of the concrete directly under the slider track along the whole side of the lanai. This did the trick. It's been 2 years and it's still holding up.
I can see by your pics you have no drain holes because your lanai's glassed in as well, which is exactly what you want. There will be drain holes in any slider track so you don't want to fill these since they allow any built up rain water in the track to escape. I would suggest you consider this fix if nothing else works. Of course, you've got to pull away any material from the concrete and clean it. You should also not apply it in direct sunlight and make sure the concrete's very dry. A cheap throw away brush works perfectly for this. And be aware it's thick and pretty sticky so going somewhat slowly during application, with purpose should work pretty well for you.
This is what I used:
Flex Seal Liquid(R)
