Forecast vs rain thunder layer

[Sebastian 686b9d2b-fd92-41aa-a32f-8a4a4d550b27]

Can you help me understand difference between model forecast and rain thunder layer?
For my location ecmwf model shows 0.5 mam rain only at 16.00-17.00 on but rain thunder layer shows rain from 13.00-18.00 on from 0.1-0.6mm
How to understand the difference?
I thought the layer shows the same data as model forecast.
Thanks for any help and sorry if the question is dumb.

Rain, thunder layer and the point forecast table comes from the same weather model forecast.
On the map rain amounts are the accumulation during the last 3 hours. In the forecast table you can choose 1h or 3h steps. Check this setting.
