I am experiencing an issue where the mat-header-cell components are not appearing after navigating

After initially loading the page, mat-header-cell displays fine. However, upon navigating to a second page, refreshing it in the browser, and then returning to the original page, the mat-header-cell is no longer visible. It only reappears after manually refreshing the page in the browser. I have spent considerable time trying to troubleshoot this issue without success. Below is the code snippet attached for reference. If anyone has insights into what might be causing this issue, please do let me know. It's worth noting that this problem occurs in production but not in development. Thank you.

 // Another code snippet goes here 

This issue seems to be specific to development as it manifests when the page first loads, but does not occur in production. The error message encountered in production reads as follows:

It seems like you may have forgotten to bind the displayedColumns array to the mat-table header in your HTML code.

You may want to try something similar to the example below:

Take a look at this screenshot of a mat-table with displayedColumns

Additionally, please check if there are any errors in the developer tools and let me know the results.

Just wanted to mention that I have successfully used mat-table in multiple parts of my project without any issues!
