So I have a 13w
uvb bulb and her basking spot is between 90-100.
There's your most likely course .
A 13W compact (even a very high output 10%UVB) version is way too weak to use in any beardie's viv.
Very little UVA and UVB will be getting to the basking spot and even less elsewhere in they viv , see this for data and comparision of UVB sources :

As AN ABSOLUTE MINIMUM you need :
>> to ditch the 13W compact
>> replace it with a 26W UVB200 AT LEAST (a 12%UVB T8 or a 12%UVB T5HO tube will be MUCH BETTER
>> move the UV source UNDER THE MESH LID (easy to hang it under mesh lid using cable ties pushed through the mesh and tightened around the reflector hood
>> ensure the T8 or T5HO tube (in a reflector hood) or the 26W UVB in a hood or dome is positioned so 180 - 200 microW UVB / sq.cm is seen at the basking spot and about 100 microW UVB / sq.cm is seen elsewhere in the viv.
I believe a long term lack of UVA is the source of the problem, along with VitD3 deficiency due to inadequate UVB.
