The cap of the extrude doesn't have the correct geometry for bending, the cap is made of an n-gon which is essenttially a few triangles and you need more edges for this. Change the cap to triangles and show edges in the viewport to see this.
Really you should make it a different way as the extrude will never create great topology for this kind of deformation, but if you are in a rush... Set the spline to be subdivided with an appropriate length for your model. On the extrude, set the cap to be regular grid, and use the same size as you used in the spline - subdivided - length.
This should give you a better result. You need to adjust the length and grid size until the resolution is high enough for the deformation, but not too high as you should keep polygon count as low as possible.
Well I would recommend using Subdivision surface modelling. So you model a low res version of it and then this is subdivided to smooth it out.
You would start with something like a cube, make it a long thin strip with quite a few segments, then make editable and select the end, this you would extrude and scale down to make the rounded end. Do this is in symmetry so you only model one side. Then you can use the bend deformer on this, then subdivide with an SDS.
Sometimes depending on usage and how accurate you need to be you can get away with using simple geometry and a volume builder, then remesh after, but the topology will not always work, depending on the intented use for the model..

Thank you! This helped a lot. If I wanted to create it in a non-rushed method what do you recommend?

Thank you this was very helpful!
