How to remove the ".," from bibliography

Hi, The citation style for "Psychological Medicine" results in the following citations (I manually adjusted it to have all-capitalized Journal titles): Utz RL, Swenson KL, Caserta M, Lund D, & deVries B (2014). Feeling lonely versus being alone: loneliness and social support among recently bereaved persons., The Journals Of Gerontology. Series B, Psychological Sciences And Social Sciences 69, 85–94. Wakefield JC (1997). Diagnosing DSM-IV Part I: DSM-IV and the concept of disorder., Behaviour Research And Therapy 35, 633–49. As you can see, there is a ".," where there should be a "." only. I cannot for the life of mine find the , prefix or suffix in the visual CSL Editor. Could you give me a hint how to find it? I clicked manually through all entries without success. Cheers EF
