Enfold Widgets Displaying Headers Only

After updating to Enfold 4.5.4, my Enfold based widgets (i.e. Enfold Mailchimp Newsletter Signup Form) and text widget with Enfold with Enfold code in it ([av_portfolio categories='4075,4076,4081,4082,4084,4086,4087,4088,4089,4090,4091,4092,4093,4094,4095,4096,4097,4098,4099,4100,4101,4102,4103,4104,4105,4106,4107,4108,4109,4110,4111,4112,4113,4114,4115,4116,4117,4118,4119,4120,4121,4122,4123,4124,4125,4126,4127,4128,4129' columns='4' one_column_template='special' items='4' contents='title' preview_mode='custom' image_size='no scaling' linking='' sort='no' paginate='no' query_orderby='rand' query_order='DESC' av-medium-columns='' av-small-columns='' av-mini-columns='' av_uid='']) are appearing as the header/title only and don’t contain the Enfold content that is to follow. This can be seen on any of my blog pages such as: https://www.strategydriven.com/2019/03/11/strategydriven-podcast-episode-35-making-change-work-if-decisions-are-always-rational-why-are-changees-resisting-2/ where the “StrategyDriven Newsletter” signup form in the right sidebar is a header only and the “FREE related content from StrategyDriven” text widget following the article (in the After Content area) are both blank.

Both of these worked without error up to the point of my Enfold update. Also note that the portfolio view code works well in the body of an article.

Any help you can provide is greatly appreciated.

All the Best,
Nathan
