Table cells not clearing

I created tables using the Bootstrap 4 table generator and I am having issues updating table fields when the data changes. for example, if I delete a record and on the form success action reload the table, the fields stay populated with the previous data.
Also, I created a search text field that provides a query parameter to the sever action and when the data updates, fields that are empty in the database do not remove the data that was in the table cell causing the records to appear to incarcerate.
For example one of the fields is “completed date”. If the table shows all records with some that have a completed date and some with a blank field and then I enter a search for a certain job. Whatever was in the cell for “completed date” stays, but all the other dates changes, but if I reload the page the records display correctly.
What am I doing wrong.
