In all of the model documentation on the site has changed the main model <div tag from 
#basicModal="mdb-Modal" to #basicModal="mdbModal".

<div mdbModal #basicModal="mdb-Modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myBasicModalLabel"
  aria-hidden="true">

<div mdbModal #basicModal="mdbModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myBasicModalLabel"
  aria-hidden="true">

i believe this is a change that came with a version update, but there is no reference to the change in the documentation.
this defiantly will cause confusion for users. In my version 6.1 angular if you copy past the html over to a project it creates a console error.
There is no directive with “exportAs” set to “mdbModal” 

then users have to figure out the have to add the dash in order to fix the error.
if only temporary their should be some warning in the documentation for users to reference.
saving users time tracking down errors caused from version changes
