Sometimes if bunnies are overweight or older and less supple they have difficulty in reaching their poops but I guess this doesn't apply to Lola!
It is possible her diet is too rich for her and she is producing too many caecs. This happened with Barney and I eventually realised his pellets (Excel Junior) were the cause. He fared no better with SS and when I cut the pellets out altogether the excess caecs disappeared. He was then fine with Oxbow Bunny Basisc T which is timothy hay based as opposed to alfalfa. There are other forum members who have bunnies who had problems with Excel.
The pellets may not be the cause of excess caecs tho with Lola, there may be something else in her diet she is sensitive too. What food is she eating at the moment?
