Hi there

I just found multiples PHP warnings when setting up a colorpicker field as repeatable and passing as default parameter an array

The fields get displayed correctly and initializes correctly with the values you setup, but this configuration causes a set of warnings all of them on class CMB2_Type_Colorpicker

2 errors "preg_match() expects parameter 2 to be string, array given" on CMB2_Type_Colorpicker lines 39 and 44
1 error "trim() expects parameter 1 to be string, array given" on CMB2_Type_Colorpicker line 46

Hope it helps to continue improving CMB2

Best regards
